I propose an update to the pun. "Geology Mine-RULES!"
Liked just for the joke , never heard that one hah and what a delivery from old Hank the genius
Ok
If you like srilankan alexandrite and blue sapphire pls let me know
0094+071 731 80 82 my whats app number... ( prasad)
Your definition of sublimation wasn’t correct. You were looking for deposition.
When you show this video to your girl, so she doesn't want a diamond engagement ring.
But it backfires.
So now you have to climb an active volcano.
And when your girl showers there goes the engagement ring....
Why not finger-ite
Nah, girls should be able buy their own diamonds or any rocks that they want. This is not in the 80s anymore since woman have rights and can work. Woman get paid higher also on average.
@@edwinkharismaprawira7607 girls usually take lower paid jobs so they arent paid higher actually
@@jonathanodude6660 With variety of jobs of course comes variety of payments. Unfortunately, woman still are actually paid higher on the same said lower paid job. Now, imagine if they actually have the drive to work to the top level. What a time for a woman to live in today if they actually have the guts to actually earn their money since they have more opportunities than man.
I actually have a blue diamond ring, but it's lab-created. I actually like that better because I got a sparkly stone in my favorite color through SCIENCE!!
Michelle Jirak It's also much more eco-friendly.
You need to move a few tons of rocks (I think ~50t) for one carate of natural occuring diamond.
@@Vulcano7965 nah not really diamond is pretty common honestly. Blue diamond maybe. It's like saying jade isn't common, I have a big piece of jade from a river for god's sake.
For SCIENCE!
Cryokenesis?
Nice! My wife's wedding ring's stone is a conflict free lab created sapphire, and it's stunning.
"Here's 6 gems much rarer and cooler than diamonds!"
"number 1: diamonds"
Hahahaaa....
Well actually red diamonds are rarer than your average Diamond 😉.
ooooneeee
r/wooooosh I guess
@@thegratercheese8457 No, not at all. Red Diamond isnt the same as regular Diamond which is what is referred to in the video, so there is no r/woooosh here unless you mean for yourself.
Specifically, Red Diamond.
rare gems always make me sedimental
Take my like and go away
Ha. Jokes
Aww,that's gneiss..
BOOOO! 👎👎👎👎👎👎👎 your family is ashamed of you no need to ask them they'll agree.
I love your videos! But there is an error at 9:17. When talking about Fingerite you said it forms through sublimation of volcanic gasses but sublimation is when a solid turns directly into a gas, the opposite would be deposition :)
Samantha Corona Thank you! I was questioning myself for moment there =s
@@amy7189 I too had a moment of mental crisis :P
+1
In my high school physics classes, I learned that sublimation could also name the inverse process (although resublimation was used too)
I don't know what's going on with the Fingerite, but from Wikipedia: "The reverse process of sublimation is deposition or desublimation, in which a substance passes directly from a gas to a solid phase.[2] Sublimation has also been used as a generic term to describe a solid-to-gas transition (sublimation) followed by a gas-to-solid transition (deposition)."
as a geology major, i thank you for making this. rocks dont get enough attention
They're minerals, Marie.
true dat
Just don’t lick them too much ;)
But they sure make you 'Rock' hard...!!!
how about the one hawkings said is hurtling towards earth? said it right before he died ,, they made him retract it but he said flat out it was coming . then he died.
10:30
“...it will just dissolve😢”
Hank sometimes puts so much emotion into his lines that it makes my heart melt
This video is worth your time, I Pumice.
"Nobody wants to climb around on an active volcano"
Me: *laughs in Salvadorean*
You will be missed.
There was a guy who just fell into a volcano, and his wife/fiancé rescued him. This just happened like a week ago from this comment.
@@clxwncrxwn He was searching for that sweet, sweet fingerite, I presume!
True ajajaja climbing volcanoes is one of the most practiced hobbies here on El Salvador
😂
I just love how flabergasted Hank gets when talking about how Fingerite got it's name lol
Well, it does have a better ring to it than Hanktite or Greeneite
Cummingtonite has a better name.
tiddies
Kid named Finger:
Like how do you get your last name to be finger 💀💀🤦♂️
Tanzanite is my favorite mineral, and I actually own a little chunk of it, though mine is light years away from being gem quality, obviously. It still has somewhat of a purplish blue hue to it, which I love.
It's quite pretty, but it's completely a fabrication of Tiffany & Co. Like Hank said in this episode, it's actually just called zoisite, and "Tanzanite" specifically is the name Tiffany gave to the blue variety of zoisite. It's rare, but not exceptionally rare. The claim that there's only one source in the entire world for it is false; blue zoisite is hard to find but there's at least seven different mines that have a decent supply of it. Tiffany specifically applied the name "Tanzanite" to blue zoisite ONLY from their one mine, to make it seem special and super duper rare when it's not. It's a shitty business practice from a very shitty company.
@@Green_Eyed_Monster
According to Mindat, Tanzanite is transparent blue zoisite, just like red sapphire is called ruby, just like black tourmaline is called schorl. Any transparent zoisite found in Tanzania is Tanzanite regardless of the color; otherwise it's called zoisite. Ruby in zoisite is called ruby in zoisite even if it is found in Tanzania.
Any transparent zoisite can be heat treated to make it blue or bluer; if that's done, it's probably still called Tanzanite regardless, because of its color. All zoisites are rare.
@@MelissaThompson432 Technically ruby isn't "red sapphire" but really just red corundum, as blue corundum is sapphire. The thing is, all blue corundum is known as sapphire no matter where you dig it up from.
@@Green_Eyed_Monster "technically," all corundums, of which there are many variations of color, are referred to as sapphire, apart from rubies.
Including pink sapphire.
The term "ruby" is semantics. Otherwise there would be yellow, orange, and green _rubies,_ rather than yellow, orange, and green _sapphires._
Unless it has a different mineral content, blue tanzanite can't be distinguished from gem quality zoisite that is blue. In fact, most blue tanzanite from Tanzania that is sold is blue because it's heat treated; it may come out of the ground brown.
@@MelissaThompson432 All sapphire is corundum, but not all corundum is sapphire. Only gemstone corundum is sapphire. But I guess that's kind of obvious, as we're not talking about non-gemstone minerals.
6:52 fusion is just a cheap tactic to make weak gems stronger
Lol I get it
The value of consumer diamonds is arbitrarily heightened by corporations like debeers who actually destroy diamonds to control global supply
Wait they destroy it? I just assumed it was stockpiled for artificial rarity not actively destroyed.
@@googleeatsdicks They destroy them because their value as industrial diamond dust / grit / whatever that they could sell today would be more profitable than eating the costs of security and storage for years while the diamonds sit around in a box on a shelf not being sold.
@AlexisBubba15 and how brital it will be
DeBeers and the other diamond companies hoard the gem quality diamonds for future sale. They use low quality industrial diamonds for industrial purposes. Remember, most diamonds are not gem quality.
For diamond knives, lab grown diamonds would be better since they have fewer imperfections, and they’re not controlled by diamond cartels. My school had an electron microscopy lab, and they had a diamond knife for cutting thin sections (less than a micron thick) on the microtome. It’s not as exciting as it sounds. It’s really just a really sharp diamond wedge 4mm long mounted in a block. Diamonds would be useless for a regular knife because they don’t get big enough, they’re too costly to machine, and they break very easily. A single fragment of grit in any of our specimens would have chipped and ruined the lab’s diamond knife. I used glass knives because I didn’t want to risk it.
Dude they don’t destroy gem quality diamonds. It was back in the good old industrial revolution, diamonds were actually quite cheap and not connected to wedding rings. Then diamond mines formed something very similar to OPEC for diamonds, where they agree to set quotas and store any surplus. Also, they launched arguably one of the most successful advertising campaigns of all time, changing diamonds from being something which was just an odd, hard rock that could look pretty to being permanently linked to marriage, something that is almost as common as birth and death. The saying “a diamond is forever”? That was part of that campaign. When you really think about it, you can’t help but be impressed, these guys managed to take an odd type of rock that was somewhat uncommon, and make it worth more than gold, inextricably link it to marriage, and do all of this in less than a lifetime.
My favorite rock is Dwayne Johnson.
Mine is Havel
lol
mine is the one I live under
Mine is Iraq
How about Steve Austin
Nah, red diamonds are caused by Sith Lords making them bleed.

Underrated comment
I've heard there's a much rarer gemstone called crystal myth, but my father ddn't really wanna talk about it
Good news, you can make them yourself !
Oh a cool part of this crystal is you can make it at your house.
You need some basic household products, mix them together at high heat, make sure to release gases and not to breathe in such gases, then cool it down in a freezer.
My dad proposed to my sister with a ring that had a myth crystal. It was the most beyutiefle ting I evr seen.
That cause it a myth
Not that rare where I'm from. Even broke people have it.
1:27 **COUGH** **De Beers** **cough-cough**
They're also behind the existence and pervasiveness of engagement rings in the U.S. They wanted to sell more diamonds, so they put out an ad campaign suggesting that guys buy their girlfriends diamond rings when they propose. And now everyone thinks it's mandatory. Sigh....
superdupergrover they finger right.

Heat treating blue zoisite should be a crime.
Yesss! This! Like, it took how many millions of years to form, and you want to change the color?! Heck no…
@@sierradanni1720 Most unheated blue Zoisite isn’t very pretty, no one would buy it unfortunately.
@@dnwr5224 I mean, that's fair... but it's still kinda sad...
I love fancy rocks. Standing amid a geological museum's mineral collection can literally move me to tears over how mindblowingly gorgeous and complex all this is, which is a feat because most of the time I'm entirely dead inside. In most cases, I much prefer uncut minerals though. Show me a collection of emerald crystals in-situ any day over the clean-cut pieces that may as well just be coloured glass.
I'm disappointed red beryl and benitoite did not come up.
Both are beautiful and single source rare gems that are pretty much exhausted in nature.
And both are really cool for many reasons.
24emerald Good point. That is *wacke.* I'm fond of Poudretteite and Ammolite, myself.
Thanks, yeah, being a Canadian I have to give a big thumbs up for both of those too...!
And being fond of fossils ... I too really like ammolite... I'm just sorry it has to be coated for best durability. Really cool single source gem though!
@Paul ... ur right, ... that is wack!!!! Considering the title
@@24emerald I have one of those very pretty Canadian ammonites. They are very cool.
The video seems to have an emphasis on not only rare minerals, but diverse and rare geological and geochemical conditions (see 10:33), so that's likely why it didn't list only rare gemstones...there's only so much room on a short list of 6 minerals.
Ah, Ichnusaite. My favorite character from Steven Universe
I'm from ichnussa!
how you know schler?
I've had a vial of rose quartz crystals sitting on my shelf for years.
wait, there are?
@@emilandreasson9670 no, it was a joke
My favorite mineral is vivianite, a deep green phosphate mineral that sometimes occurs in shell fossils, turning them a gemmy green 🙂
It also used to be the basis for Prussian blue!
This is basically: You wasted 10k for a stupid ring that is basically worthless and isn't rare at all.
You can thank the Luxemburg gang for artificially raising the prices of diamonds.
yep! No such thing as diamond engagement ring till DeBeers robbed Africa of it's diamonds. It's all a marketing ploy to sell you a NOT rare, cheap sparklies for Thousands of dollars!! It has worked quite well!
@Rulya Ard Mhacha Farley This is just my opinion. I don't like being scammed for a stupid rock that could lead to me being homeless.
Anyone that spends more than 1K on a ring should seek a financial advisor
I'm a woman and I've never understood the appeal of diamonds. I mean okay it's sparkly but it's just a rock.
Give me something with more substance. A photo of my wife or something that reminds me of her would be more meaningful even if it cost $0.50 out of a plastic egg surprise machine.
Diamonds are not rare at all. De Beers, which is a monopoly and as such is banned from doing business in USA, keeps a tight lid on supply. They have billions in storage to keep the prices high.
My girlfriend collects cut gemstones and we go to all the jem and mineral conventions in western US. I'd rather have a peridot ear ring than a diamond any day...
Most black diamonds for sale in jewelry stores are just heavily included stones that are treated to be black.
They haven't been a monopoly for around 3 decades, and they've never been 'banned' from the US. The US has zero authority to ban businesses. What foolish person told you this?
@@Novarcharesk
De Beers executives risk arrest if they visit the US. Gems from De Beers mines are sold in America, but not under the De Beers name. The company cannot openly do business there while charges of price-fixing remain outstanding.
There, you've been educated on the facts.
@@Novarcharesk they can legally break up monopolies. That's why debeers is based out of London
Legally dismantling businesses I don't like is okay, because I don't like them.
Thank you for this, I'm a geologist's daughter, and haven't seen such an awesome geology-oriented presentation in 30 years or so. With the added plus of magnificent geology puns in the comments. Thanks!!!!

I know muscle Hank can crush all of them like he crushes diamonds
Diamonds are very brittle, actually, you too can crush them
Also, they burn!
@@proto3139 They burn because they're made of pure carbon. Without any bonds with hydrogen or oxygen, they're technically inorganic.
I love videos about gems and minerals! We need sci show geology!
I just want to take a moment and appreciate SciShow and Hank Green. My anxiety was spiking, and the show I was watching to "wind down" was absolutely not doing that, ao I just hopped on over to some minerals and now I'm so relaxed. Thanks Hank, I appreciate you and all the work you and your tea does. Man, science is cool.

@@XamiNaxamis Omg that would be so amazing
Moldavite would've been another great mineral for the list. It was formed by a meteorite impact 15 million years ago. Although probably not as rare as these gems, it's a rare occurrence to say the least.
My favourite ring is a silver band in the shape of a branch, with a moonstone embedded in it and it is a symbol of my marriage to my best friend. Simple, but priceless.

Diamonds are overrated, to be honest.
They are mechanically useful, that's about it.
@@kindlin Agreed, it is one strong rock, but jewelry companies withheld the supply to make it seem 'rare and priceless' to inflated the cost.
Not to mention that they marketed it so good that everyone now thinks they are a necessity for every engagement.

My wife insisted on a diamond for her wedding ring. Myself knowing how common and extremely overpriced white stones are I went with a 1 carat blue diamond. Far more rare and beautiful. It matches our relationship better. 1 in a million.

What about my girlfriend? She was the coolest and rarest gem I ever found!❤️
Unacceptable. Get a grip.
Is This a real human being
This is probably the first RUclips comment that talks about a relationship and isn’t depressing
I used to live in a town right next to mono lake. It was an extremely salty lake. There were ice pillars just everywhere. I mean the lake was so salty it could be considered saltier than a 12 year old CoD player. It is a great vocation area. It is near mammoth mountain, a famous ghost town, and some other really cool things.
Jesus Christ, Marie! They aren't rocks, they're minerals!
beat me to it haha
I thought your username is "octoling", I would have splattered you.
@Shawnaldo75 it's a reference to Breaking Bad haha
Shawnaldo75 No, rocks are made out of minerals.
single-mineral rocks aren't too common.
@Shawnaldo75 That doesn't disprove the fact that minerals aren't rocks.
Rocks are a composition of (multiple) minerals. Only under rare circumstances you get a rock with >90% made out of only one mineral (e.g. Quartzite, Dunite).
But then there still are other minerals in these rocks.
Minerals are not a specific type of rock, that's BS!
It's like stating one sheep is only a specific kind of herd.
alexandrite is still the coolest gemstone imo
There are artificial versions that are really pretty too, even "alexandrite" glass (iirc neodymium gas infused) of which there's everything from beads to figurines. Doing a RUclips search for "neodymium glass" or "alexandrite glass" should show a lot of pretty color shifts.
Wrote the same thing above. Totally agree.
I have an alexandrute rung that is nearly 50 years old and even though the stone is not genuine it is still beautiful. I don't like the ones I've seen in recent years, when I've been able to find them. Most people who see my ring think the stone is an amethyst & they've never heard if alexandrites.
Opal is the best
It's also extremely rare, and when you do find a source of it, it's absurdly labor intensive to mine out of the ground.
You: These 6 gems are really rare.
Thanos: Hold my beer!!
Blue zoisite is my favorite gemstone. So underrated yet so pretty!
Green zoisite . Cut, matches the best Columbian Emerald I've ever seen..
This topic was awesome, would like to see more like it
Yea, diamonds are over inflated under supplied, abundant hard rocks anyway.
And can simply be manufactured...

I love your videos btw.
I ❤️ nerds.
My first gift from my now husband of 22 years, was a tanzanite and diamond ring (not lab created). After we married he bought the matching necklace for our 1st anniversary. Since then, besides other jewelry (I’m a Taurus ;), he gave me a lovely alexandrite (lab created) later mounted into a pearl enhancer pendant (college graduation gift). For our 15th anniversary was a 1.25 ct. black diamond solitaire he mounted in my grandmothers old wedding band and 0.75 cts each- black diamond earrings (lab created). For our 20th anniversary a 1.25-ish ct. blue-green diamond solitaire (lab created). My favorite part is that he knows I’d prefer solitaires so that I can always change my “ring” and studs with enhancers, especially antique ones, we buy when off exploring some other city or spending the afternoon perusing our local dealers :). The fact that some are lab created makes me even more happy knowing that they weren’t apart of someone else’s suffering and they are better quality than most :).
SciShow @ 9:18 you say sublimation is changing from a gas to a solid but that's not true. It's changing from a solid to a gas.
The term you're looking for is deposition
the correct term is Deposition
Chem major here: sublimation can mean solid to gas AND gas to solid. It goes both ways.
Summarizing previous scriptwriter’s response: the original academic paper referred to the substance as sublimate (noun), referring to the definition that compounds turned into gas then turned into compounds
I adored this. Thank you so much for it.
Thanks for the shoutout on the camera course. I'm already a paid subscriber to SkillShare and I've been wondering how cameras work.
Smoothest Ad transition I’ve seen on this channel yet, good on you Mr Green
2:06 _"Pink Light"_
*[ T R I G G E R E D ]*
This video reminded me that i have a mineralogy examn i have to study for 😭
It's seriously comforting to me to watch you speak about something so unrelateable so excitedly :)
Interesting.
I recall watching a program where they showed raw and cut Tanzanite, but imo the raw version was the more impressive, with it being somewhat cubeshaped and changing colors from red to blue to violet, that's way more interesting imo than a regular blue colored gemstone.
I used to buy my girlfriend a matching set of earrings, tennis bracelet and necklace of a given gemstone/black pearls that kind of thing. One year I saw some Tanzanite and went online to see what it cost...
Never mind.
Let's be honest here, out of all the people over at Scishow as great as they are, Hank DEFINITELY has the best taste in style. That shirt is pure flames.
Yess!! This mineralogy content I’m thriving and need more!
We just spent so much money at the gem and mineral show.
"Hey we found this super rare gem that changes colour depending on how you look at it"
"Cool, let's heat it up so it's just blue"
I got to see some raw tanzanite while in Tanzania. It quickly became my favorite.
Not all Tanzanite shows pleochroism. Most of the time it's the brown, reddish brown and purple/ lavender crystals that get heat treated. MoreGems RUclips channel is awesome if you enjoy watching rough be cut into 💎. He has a video where he heat treats a brown Tanzanite and cuts 2 beautiful blue gems.
Really cool video! Very professionally made content that kept my interest.
This was probably the best ad about skillshare I've seen, i legitimately thought you were praising photographers
Here's a good topic to cover: What exactly is solubility, and what determines whether a substance can be dissolved by/into another substance?
Something something polarity
You should have imcluded Benitonite:
Benitoite occurs in a number of isolated locations globally, but gemstone quality material has only been found in California at the Benito Gem Mine where it was first discovered. It has been correctly identified in Montana, Arkansas, Japan, and Australia although they formed under slightly different conditions and only grow large enough to be considered an accessory mineral. In 1985 benitoite was named as the official state gem of California.[7][8]
@SciShow correction at 9:15, the chemistry term for a gas turning directly into a solid, skipping the liquid stage is known at deposition. Sublimation is when a solid turns directly into a gas.
As a mineral and fossil collector, I really really appreciate this. ❤
THIS CHANNEL ROCKS!!!!!!!!!!!!!1
No.
I love the passive aggressiveness of THEY ARENT SPOKEN ABOUT. AT ALL.
Man, just imagine all the cool minerals that exist in tiny, tiny traces, which no one has ever seen. Or imagine all of the kinds of minerals that are allowed to exist under the laws of nature, but which haven't ever existed anywhere in the universe before.
Sardinia rocks! No, seriously, it's basically just rocks, i was born there so trust me, i know!
Ha, Jokes!
@@bs-vo1ii ok
Sublimation is the opposite of what you described: turning straight into a gas from a solid. The term you were looking for is deposition.
Erik Mänd Summarizing previous scriptwriter’s response: the original academic paper referred to the substance as sublimate (noun), referring to the definition that compounds turned into gas then turned into compounds
Its both
Nice presentation and quality information. Being a tanzanite dealer I found it very interesting.
That ad transition was SMOOTH.
Diamonds: well, well at least they're not unbreakable like me
Diamonds : CONGRATULATIONS! You wasted 90% of your money for a ring with a worthless stone and now are broke.
Diamonds actually chip. So, definitely breakable. They're just hard to scratch.
@@Cypresssina Do you get the reference?
And if you want to see some incredibly rare crystals, you become a chemist. I've produced crystals of some very weird compounds and sometimes you only get a single on ever. And then you get to shoot x-Rays at them! :D
I suggest honorable mentions, although some of them are technically rocks, but still used as gems.
- Nuummite: A metamorphic rock composed of gedrite and antophyllite. It comes only from Greenland and displays iriscendence when cut and polished.
- K2 Stone: Granite coming from near the peak of K2, it contains blue spherical spots of azurite.
- Quantum Quattro: Combination of malachite, chrysocolla, dioptase, shattuckite and smoky quartz only coming from Namibia.

When this video first started, I thought I'd somehow clicked on an old SciShow vid - Hank was so enthusiastic, he looked younger than normal!
Love your channel and love this video! In the quest for ever accurate information, you made a small mistake when talking about the Fingerite. The process by which gas turns directly into a solid is "Deposition" not sublimation. Sublimation is the process of a solid turning directly into gas.
PancakeMixNZL Summarizing previous scriptwriter’s response: the original academic paper referred to the substance as sublimate (noun), referring to the definition that compounds turned into gas then turned into compounds
Sardinia? Reminds me when i beat up the boss of the italian mafia back in 2001 and became the leader of his gang
There's also hiddenite, which up until quite recently was only found in Alexander County, North Carolina. There's even an unincorporated community/census-designated place there called Hiddenite.
Tanzanite is one of my favorites! Along with Morganite, Alexandrite, and Opals.
me: got half a pound of star garnet on the counter (can only be found in 2 places) lol
De Beers is shaking
I appreciate his enthusiasm
More of these lists pleaaaassseee!!
Hank is the best
Diamonds are for people who fell for the Marketing Hype 😂
My husband asked me if i wanted a dimond or a house i said a house.
Yesss!
This and the Infographics show are my favorite RUclips channels
Tanzanite is probably my second favorite mineral.
Close second to emerald, just gotta love the green color and how it's mined in my home state, North Carolina.
I got an arcanite crystal from thorium today.
Diamonds are only useful in machine tools, nothing else
And its beauty, though that might be stretching the definition of “useful”.
Yeh lol, whetstones, light focusing, and tools, end of story
Prisms?
@@KnakuanaRka They are actually very boring. I'd rather have garnet or emeralds for jewelry.
Really excellent report!
Love the enthusiasm
Talk about diamonds got me to perk up. Pretty much listening for Steven Universe and possible characteristics to compare.
I was hoping they were going to cover alexandrite. 😢
@Gulgathydra ... I agree alexandrite is a cool gem.!
I know! I can't remember how much I spent on a tiny super included one. I actually thought they were rarer than Tanzanites.
@Lori K ... yes, by size and quality it is definitely more valuable. Keep in mind it is now synthetically grown as well. And even natural ones are usually treated for color.
@@ItsLoriK It's not just the rarity, it's that they change colour under artificial light!
I'm sure you know that, I'm just stating it because I think that warrants its inclusion in the list.
My engagement ring is alexandrite :D
