Is This Jadeite Or Nephrite Jade? Any Interested Buyers?


Boulder With Partial Window Polished

Question : My name is Mike XYZ, I own a new mine where I am producing rough jade. I have not had the jade tested yet so I don’t know if it is nephrite or jadeite. I would like you to see the pictures of the rough and if they look interesting to you I can send you some samples.

Material Is Quite Translucent

If you like the quality, I am hoping that you would be interested in buying from me or helping me market my rough to any customers you may know that would be interested.
I look forwards to hearing from you.

Best Regards, Mike (California, USA)

From the photos you shown me I would deduce that your jade lot is nephrite jade.  Nephrite jade is fibrous while Jadeite Jade is more granular.

While you have not indicated the location of your mine I would deduce that it is in California, USA.  USA does not produce any Jadeite material but Nephrite can be found in a number of places.

You can do a quick and dirty test on your jade lot.  Buy a small ‘pointer’ jade quartz (probably will cost you $1) and do the scratch test.  Read my post on Mohs Hardness to understand more.

Simple Scratch Test

The hardness of Nephrite is 6 while Jadeite is 7.  When you scratch you specimen stone examine it with a loupe and look for the deep indentation.  If the indent is quite deep then your stones are Nephrite (or some other material but not Jadeite).  However, if you cannot scratch your stone and its hardness is about the same as quartz, then you cannot deduce that it is Jadeite.  You can negate Nephrite but to positively identify that your jade lot is Jadeite you have to do other affirmative tests.

I am putting a number of the pictures you sent me.  If there are buyers then I will direct them to you.

Alternatively you can try to exhibit your jade lot at Tucson, Arizona.  Every year for the month of February Tucson Gems Fair come alive for the whole month.  There are many rough stone dealers there too.  Tucson Gems Fair attracts over a few million visitors every year.

There is the ‘open’ fair where you display your stones in the open air.  Or you can book a booth through the various organizers.  Perhaps you can scout it out this coming February and see whether you can find some buyers.

I have exhibited there before and could get some Jadeite customers.  It is worth your time and expenses to go if you have a lot of stones to sell.

Feel free to drop me an email if you have further questions.
