~ Exclusive D-Block Tanzanite ~
About Tanzanite : Tanzanite
is a trade name that was first used by Tiffany and Company for gem-quality
specimens of a mineral named zoisite with a blue color.
The name
"tanzanite" was given because the world's only known tanzanite
deposit of commercial importance is in northern Tanzania. The name
reflects the gem’s limited geographic origin. The mines are all located in an
area of about eight square miles in the Merelani Hills, near the base of Mount
Kilimanjaro and the city of Arusha. A similar stone from the same lot was certified by IGI in the past and below is the report ; although the gem lab did not mention anything about the treatment or heating but I believe these tanzanites may have been through the process of heating. Please note : The Tanzanite in this listing does not come with a IGI certificate and neither we will get it certified from IGI since it takes a long time, customers can get it certified on their own, we would send a certificate from a local gem lab on request.
