I just did a specific gravity test with my crude apparatus and the result was around 2.40. Not high enough for jade but that excludes mammoth ivory (1.77 specific gravity).


Hi Marcos,

The material which Joey thought it could be was fossilized mammoth tooth, which is NOT ivory, but petrified tooth. I have handled a genuine old mammoth tooth bottle, and found it to be both cold to the touch (like stone) and heavy.

But reading the follow-on posts, I agree that it may not be jade at all. George's suggestion of heat-treated chrysocolla would explain the blue residue on the interior.
