Tanzania Sapphires - $60 to $300/carat
Locality: Tanzania, Africa

 

This Sapphire is unheated and it is usually not large in size (3-6cts is fairly large), as most of this material is under 2 cts. This old material from the Songea area... The colors range quite a bit depending on the light they are viewed in, they are not quite color change (at least I would not say so for most of them), but there are some very strong color shifts in this rough..

There are reds that some people call Ruby, but in my experience, when they are cut the color, while red, usually has too many other colors (or shift, usually blue/green, heating can sometimes take this out) in it to be called Ruby.

I just call it "Fancy Sapphire" and most of the jewelers I do business with are quite happy with this material. It needs some orientation for the color you want, and expect some mixing, it cuts well in most Brilliant designs.
