Thank you for watching my video! This channel would not be possible without incredible guests and educators like Shane from Freshwater Jade. Who should I interview next?
For identifying rough jadeite it's true you can't rely on looks entirely but the way the surface of the stone is weathered, the colour and the texture as well as the weight of it do give some clues wether the rock is more likely to contain jadeite.
This is the most informative channel I’ve found on Jade. I’d love to see a a channel this comprehensive on gem grade Chalcedony- Gem Silica and Chrysoprase. Also, something on Bacan from Indonesia.
I do wanna write this down that a jade rough CAN be dyed or treated but the events of that happening is very rare and happens only in Burma and China for sure. As for yellow nephrite jade, it definitely exists but is also rare and so far I’ve had acquired only one that leans more towards golden yellow over 80% the piece and seems almost exclusively in certain regions of China and are usually found with inclusions and dendritic patterns. So chances of getting a 100% full body yellow nephrite piece is just as rare as mutton fat jade, and heard it can fetch a high price too (just not nearly as high as mutton fat of course lol)
I have a pendant carving that is orange and I can identify a bat carved in it and either a dragon or i think a foo dog but have no clue what it's made from I think its either jadeite or nephrite 😅 really is hard to figure out
How do I send a picture of this? Can you give me a place to send a picture of this cause this right here? Looks like a real Jade, and it is not too big, but it weighs like 5 pounds. So let's change that story, and it's not really that big. I need to send you a picture to identify this and uh. Please and thank you
You got the MOHS hardness for nephrite and jadeite backwards . Jadeite is a metamorphic rock with pyroxene group minerals , and is harder (6.5 to 7) than the amphibole group metamorphic rock nephrite (6-6.5).
Hi, thank you for your comment! In the video, I state that nephrites hardness is 5-6 whereas jadeite is 6-7. However, this isn’t **always** the case. Both jades have a wide range of hardness, and some nephrite (for instance, Washington nephrite) has been found with a 7 hardness. Jadeite jade with high omphacite content may be as low as a 5 in hardness. Testing the hardness of an aggregate, especially with directional fibers, is not necessarily a straight-forward thing. In my opinion, hardness testing is most useful when separating jade from serpentine, bowenite, and soapstone.
You didn't talk about how difficult it is to cut jade with a diamond saw. I know I have a piece of jade when it takes 15 - 30 minutes to cut it in half.
@ngwillard Most of the jade I have is from British Columbia, and is all nephrite. I have one small piece I found at jade cove. It was about 2.5" long and pencil shaped, maybe 1/4" around. I cut it in half with a diamond band saw. That took the better part of an hour and left the motor smoking. I made a cab out of one piece. It's jet black and has the typical low gloss surface of jade.
Great question! Gemologically, “cat’s eye jade” isn’t typically considered to be nephrite jade. Nephrite jade is composed of actinolite and tremolite. The nature of these crossing fibers is what makes nephrite superior in toughness. However, cat’s eye jade can contain both actinolite and tremolite as well - but to have chatoyancy, the fibers must run parallel, meaning a difference in toughness. So, essentially, “cat’s eye jade” is made of the same minerals as nephrite jade, but the internal structure is different. Some will still consider “cats eye jade” to be nephrite, but some call it “cats eye actinolite” or “cats eye actinolite-tremolite.”
@@JewelsoftheTrade Thank you so much for clarifying this for me! It was hard finding an answer online as some say it is nephrite while others say it isn't. Now I understand that the main difference is the direction in which the fibers go, which is what does or doesn't give it that chatoyancy effect/determines its toughness. Thank you so much again!!
Since this question’s already answered, I recall a quote somewhere which describes nephrite and cat’s eye jade formation basically as “baked not fried” which can basically describe any rock with the same chemical formula that undergoes different formation to become what it is now.
Hi there! GIA says nephrite jade is a 6-6.5, so you’re not wrong. However, nephrite (like many gems) varies a lot in hardness. For instance, Big Sur jade tends to be less hard (closer to 5) and GIA (to my knowledge) has never published on that material. There have been nephrite jade samples testing around a 5, and I’ve even personally seen genuine jadeite jade (which is usually harder than nephrite) be scratched by steel. Both jades honestly just vary a lot in many characteristics, and it’s important to remember that hardness rating is based on the research of a limited sample of material. It’s not “set in stone.” (Pun intended 😂)
Yes! Toughness refers to resistance to breaking, whereas hardness refers to resistance to scratching. Jade is the toughest gemstone in the world, but diamond is the hardest gemstone in the world. In fact, jade can be 24-48x harder to break than a diamond.

I have started carving jade myself recently. It's quite a process to figure things out.

Started wearing nephrite instead. I’m back to my silky jadeite
We have mine of Serpentine and now mixed niphrite I am confused in different colours😂
Thank you for your detailed explanation and effort.

What about Edward s Black Jade. It is opaque. I have a piece that I cut a 1/4 inch slab off shows no green when a light is put to it
What if you came up with a good piece of jade from a unknown souce?
Very helpful to identify the jade
I have dark serpentine like yours and noticed that neodymium magnets stick to it. Is that common?
Its have Fe in it, which is normal for nephrite jade, it’s a gemn sepentine
I have a pendant carving that is orange and I can identify a bat carved in it and either a dragon or i think a foo dog but have no clue what it's made from I think its either jadeite or nephrite 😅 really is hard to figure out
I have what I saw here, but who should I sell it to?
Do you sell this kind of stone here? I like it very much. I want to collect
Hi, I have rough Jadeite Jade Type A from Indonesia, do you interested ?
I have puchased acanadian nephrite jade and Local Philippines Jade, would you be so kind to check it?
Can u help me identify My artifacts if it is a jade?
May I know what this is

Wow 😲 I hate that these stones look similar but it's all in it's touch, harness and chemical composition that set them apart.😅

So is actinolite jade with the cat eye effect actually jade? Or is it a jade replicate despite having actinolite which is in nephrite jade?

We have Jade here in NZ
At this point I'm confident I have found a lode of jadeite,
i have much jems stones and videos i want to contact u?
I’m pretty sure Nephrite has a hardness of 6-7. Not 5-6 which is actually pretty soft. That’s why steel at 5.5 won’t scratch Nephrite.

Shane, Jade and Jadeite can be banded FYI, jade are metamorphic rocks.

Dommage que je ne comprends pas un mot d' anglais !

I have jade
toughest gemstone but has a hardness scale of 6… ???
Yes! Toughness refers to resistance to breaking, whereas hardness refers to resistance to scratching. Jade is the toughest gemstone in the world, but diamond is the hardest gemstone in the world. In fact, jade can be 24-48x harder to break than a diamond.
This confuses me too😅
