I have put myself into a problem. I have seen a rough stone sold by
several dealers as black nephrite jade from Austrailia. It has a
semi concoidal fracture. It is absolutely black, there is no green
on the edge of a wedge with no hint of transulency. It has no grain
as most nephrite does. I can break small chips off a corner with a
light tap with no hint of a fibrous structure. It is not nearly as
tough as any nephrite that I am familar with. It will take a
beautiful mirror polish.
The most distintive feacture is where a surface has weathered. It is
a solid red brick rust color.
My problem is that it is obviously not truly nephrite and I bought a
quantity of the material expecting that I could find a reference to
its true identity. So far, I have failed. Does anybody know what
this material is?
I know it isn’t nephrite, and I can’t sell it if I don’t know what
