I’ve faceted obsidian, hematite, tiger’s eye, and ametrine with just sandpaper and diamond sharpening stones. It takes less time than you might imagine
This is how I started, with simple grinding tools and sandpaper. I was curious about a small stone I had and wanted to experience precision stone shaping. From there I made a few tools, bought more and now I facet, cab and create sterling silver jewelry by recycling scrap, much cheaper than buying sheet/wire sterling.
That was pretty cool. I used to use my Dremel to polish small rocks. I certainly couldn't cab I could polish and I had many bits and sanding pads from 60 grit to 10,000 grit. They were about 2 inches but came up to 4 inches and I did really well for someone that only had one hand. The fire opal looked awesome! And I'm sure it was the easiest to get smooth! The iolite is pretty hard and will polish well, but is pretty hard going with a fordom. And you did pretty good with the obsidian too! I never had luck with obsidian, but I usually cut myself up too! Thanks for showing this, because it can be really helpful and easy for beginners!
This is SUCH a great video. I've been wanting to try exactly what Preston did in the video. Preston has inspired me to give it try. Thanks for posting! 👍
Ooowee! I'm surprised you didn't shatter your obsidian and opal from thermal shock! I used to use a slow drip of water above and a plastic tray of water below when I carved them. I'd dip the stone about every 30 sec to cool it. If you get into gemstone carving you'll want to get a thinner handpiece for your flex shaft. Like something from a dentist supply. With the larger handpiece after an hour your hands will still feel vibration if you snap your fingers or touch anything. It's really weird. Can't be good for the hands! With polishing obsidian you want to be really systematic with the steps.. progressively finer grades of sandpaper then up grades of polishing compound up to the best mirror finish diamond compound. Clean it thoroughly between each step. Let that vibration get out the grit and compound too, not just water and soap. You want every speck of compound off that stone before going to a finer grade or you'll get a noticeable scratch and have to grind it off and start again. It's real finicky! Opal in matrix is tough too because the matrix and gem material is so different (you know that!) So if you're not going to just grind it away it's better to use a cabbing machine rather than the flex shaft. It'll be uniform that way where a flex shaft bit will eject chunks of matrix faster than the opal. You also really don't want to work with opal dry. Not at all. If you can carve in a slurry of water and diamond paste that's ideal. It carves faster and cooler and prepolishes it. Doesn't seem to require as many steps as obsidian does to polish. It's going to be super porous even at the last step. If you have to stop before you get to the final polish keep it soaking in water. Both obsidian and opal cut like butter though. It's really satisfying, especially if you're doing something with a lot of fine detail. If you like those you might also like Tagua Nut, a vegetarian ivory lol. Carves the same and you can stain it with colored inks and dyes for scrimshaw. I've written you a book here lol. Hope it helps!
yep. i dove in like this on a chunky ethiopian opal. it would get very hot, until i decided to cool it w/ water. it flew out of my hands many times, one time cleaving it in half. bummer. so, while it's fun to dive in, it's best to know the basic dos & don'ts of such undertakings.
9:30 I’ve been working opal with rotary for almost a year now and I must say from day one to now I’ve massively improved. I do agree a cabbing machine is best(I’m saving up for one but for now a rotary tool is great for what I need) but what I’ve learned with the tools is there’s many ways to go about this process especially with free-form pieces. Sometimes even a 3-4 day tumble can easily make the experience so much easier. I find that a good pre polish is key for the best polishing experience with no can machine and just the rotary tools as after I began using it my polishing results were DRASTICALLY improved than jumping straight from sandpaper to polish. Hopefully I’ll get the machine sometime soon but improving just with the rotary tools is equally as motivating 💎
Thanks for the fantastic explanation! I'm totally visual as far as learning goes. Respiratory protection is what you were searching for in regards to the mask, I believe. 😆 I have a Dremel and an intimidating pile of raw gemstones that look at me from the corner. Now I feel more confident in tackling this task.
Hey, I just started watching your videos this morning and I know they’re like four months old but I just wanted to say thank you because I am just starting out and I’m trying to learn different ways and how things should be done and how they could be done I’ve only watched this one video, but I am definitely a subscriber and I will watch all your videos and again thank you very much. Take care and God bless great job.
You did a great job, I did it the same way when I first started, and now I use a flat lap. It's not as expensive as a cab king or other machines. Awesome video and great information.
Thaks! This is really inspiring! I’ve been wondering how I can make my stones shine without buying a lot of expensive tools. I engrave stones and have only done natural stones so far. Will definitely try this to add some depth to the art 😊
Thanks. It was very helpful to keep in mind. I want to try more in my gemstone adventure. You're right, you can surprisingly do a lot without the "proper" tools. Necessity is the mother of invention after all.
in a similar vein, i'd love to see a video on gemstone dice! highly recommend Hedron Rockworks for the beautiful D20s & cutting & polishing process videos they make.
That typeof mask doesnot stop respirable silica. You need to have a respirator that is made specifically to block silica dust with replaceable filters.
Can you please do a video on Astrophyllite, Arfvedsonite and Anthophyllite. I have several specimens that were sold to me as Astrophyllite, but then thought (based on several RUclips videos and hundreds of Google Image examples) that what I had was Arfvedsonite. However, I have since learned about Athophyllite, and I am about 95% sure that this is what I have. I am also sure that the vast majority of what is sold as either Astrophyllite or Arfvedsonite is actually Anthophyllite. It would be good to get a reputable source for a video showing the differences, as sharing the Minedat and Epigem info pages is a bit hard for some of my customers to follow.
This is what I'm trying to do as well however I'm afraid that I'm not using enough water or able to use enough water. I'm new at this so I'm not sure how much water is a sufficient amount. Also what kind of polish is being used because my Drexel came with a redish polish that actually turned one rock red and I can't get it off. It looks neat but it's not natural to the type of stone which I'm trying to keep them as natural as possible while still shaping and polishing.
He stopped at 2k grit. With the hardness of a 7.5. You should be up in the 80k grit range. Diamond paste works well. If you run each stage of grit properly by the time your up to 80k grit your good to go. If you want or can you could go up to 100k grit of diamond paste and your good to go. There is aluminum oxide paste than cerium oxide paste. But I found diamond paste is the best option.
For the ultrabasics you really don't. I started out with the same sandpaper kit he's using(under five dollars at walmart btw) and a piece of wood to set the sandpaper on. Weirdly enough, you can ACTUALLY cut a decent looking cab like that with enough practice and patience. 1/10, slowest. Job. Ever. Do NOT recommend.
Could you do jet? I dont have whitby so my attempts to polish lesser quality jet have been foiling me. Do i need boiled linseed oil and lampblack to sucessfully polish jet to a mirror finish, or am i grasping at straws? Thanks for any help.😢
Why take the sharper edges off the stone? I know it makes it more appealing but doesn't it take away from the natural look of the stone? Does anyone know which is favored as far as for selling?
Honestly pretty crazy how much bang for buck he is getting living in the middle of nowhere. I’ve seen much smaller and less opulent houses/mansions sell for more than that in the U.S. Location, location…
Eh, could achieve the same result with a tumbler. Fire agate or opal would need a dremel. I am dreaming of making a human powered machine to facet gemstones.
If you hit a big rock with a hammer you will get nice jewelry sized pieces from the Little Rock’s, good friend Steven Quentin Dickey mining company - django
Nice vid, but I'd use a much more serious face mask. Cutting or polishing minerals dry is not to messed with. Get the best mask you can get and use a extractor with a damn good filter. I'd never dry cut because it can be very dangerous. Search for how dangerous minerals can be before you cut them.
Totally, best way to take longer, get a 2nd rate finish, and screw you tips out and overheat stones Good job Edited to add, in his defence he's does state he's a novice
Look for local clubs in your area. Where I live, (San Diego) there is a lapidary club that provides free use of cabbing equipment when you join the club and they also have classes in basic lapidary techniques. GIA also has lapidary classes and certification.
Soo many mistakes I don't know where to start. I came believe you're not using water on EVERY pass. Plus you don't want to heat up the stones, nevermind you just keep doing you boo boo.
Ur not goin' to have a lot of dust if u do this the correct way their genius! Ur posta use water when sanding gemstones or any stone for that matter!! Educate urself before u go tryna teach ppl!

How'd it go?

You did a great job, I did it the same way when I first started, and now I use a flat lap. It's not as expensive as a cab king or other machines. Awesome video and great information.
i think there are a few how-to vids on DIY flat, water drip laps.

You help me lot. This video is exactly what I was looking for. Thanks a lot.
nice, simple tools and also you can do all of it under water to avoid all dust
in a similar vein, i'd love to see a video on gemstone dice! highly recommend Hedron Rockworks for the beautiful D20s & cutting & polishing process videos they make.
Oh wow! I need this video! I have a dremel only and am really looking to start polishing my geodes, maybe with a flat lap, but this will be so useful!

You need to have a respirator that is made specifically to block silica dust with replaceable filters.
Hi! I loved your video so much. What is the machine you are using ?
Welcome to Moh's!
Is that a Foredom rotary tool you are using?
"Special tool to lock it."
Chuck Key-they make them everyday. Just take your tool with you to avoid doing math when you need a new one.
Definitely need to use water, I never cut without water
This was awesome, thank you!

Hello….,,I’d love to see a show on how to tell the difference between Arizona turquoise and Persian turquoise, thank you 💫
Tim
That's sweet, I gotta get a dremel tool. I been hand polishing with minimal tools, it's a nightmare. Lol
Im right there with you wanting a cabbing machine. I could also use a lapidary saw😂
Thanks for this demonstration
We're waiting for some collaboration with CabKing!!! 😂❤
Any advice on polishes/brands? I just tried one I had and it left my stone red🙃
For the diamond bits/burrs what brand/set is a good pick? Amazon can be iffy so actual options are probably best here😂
They have lots of cheap Chinese crap.
It's downright insane how much you look like one of my friends back in the early 90s 🙂 Besides that: awesome video, man! 👍
This is what I'm trying to do as well however I'm afraid that I'm not using enough water or able to use enough water. I'm new at this so I'm not sure how much water is a sufficient amount.

Yes I was planning to buy that of tools, I have found a special rock.
Why you don't use water, you need to cool down the temperature and make the tools life long longer when you use water
I'm glad you are very informational. Thanks you sir"
Thanks and welcome
Less a beginner’s guide than a beginner’s first attempt.
Great show.
What is that red colored adhesive that melts to a stick to stick on to a stone so you can hold it better while hand sanding a stone?
how about a video on terahertz stone?
Great video, I have e a fossil stone that I got from india it has turned black, can you suggest me how should I get it's orginal color back ?
There should have been way more discussion of silicosis and how to protect against it.
What kind of polishing medium is that I have some rocks that I found on the beach that I’m pretty sure just need the polishing medium to be perfect.
He stopped at 2k grit. With the hardness of a 7.5. You should be up in the 80k grit range. Diamond paste works well. If you run each stage of grit properly by the time your up to 80k grit your good to go. If you want or can you could go up to 100k grit of diamond paste and your good to go.

I like how he said you don’t need any specialized tools as he’s using specialized tools

Weirdly enough, you can ACTUALLY cut a decent looking cab like that with enough practice and patience. 1/10, slowest. Job. Ever. Do NOT recommend.
its not specialized, they're general tools

Just remember where you came from and the journey along the way.
what kind of polish was used on the stones
I do the same at home 👍
Eh, could achieve the same result with a tumbler. Fire agate or opal would need a dremel. I am dreaming of making a human powered machine to facet gemstones.

Bro you need to be using water with your Dremel. You are going to waste a lot of bits without it. It's obvious you've never done this before.
Totally, best way to take longer, get a 2nd rate finish, and screw you tips out and overheat stones
Good job
Edited to add, in his defence he's does state he's a novice
He may be using water as there is a spray bottle. It may just be edited out
Imagine sharing a suggestion without being a d*ck about it… uh, what a strange notion
"Whoo-Hoo it is dusty!" Is what he says.
He says 30 seconds in that he hasn't done it before....pay attention.
Also has a spray bottle and stresses it's use at 4:10👍🏻
I want to be a lapidary
Look for local clubs in your area. Where I live, (San Diego) there is a lapidary club that provides free use of cabbing equipment when you join the club and they also have classes in basic lapidary techniques. GIA also has lapidary classes and certification.
That's awesome!
Soo many mistakes I don't know where to start. I came believe you're not using water on EVERY pass. Plus you don't want to heat up the stones, nevermind you just keep doing you boo boo.
Bro get cutting blade instead of diamonds bits.
There is a reason people do lapridary work wet. I'm just saying, for your lungs' sake...
Ur not goin' to have a lot of dust if u do this the correct way their genius! Ur posta use water when sanding gemstones or any stone for that matter!! Educate urself before u go tryna teach ppl!
Next time polish the daimond
