GIA's first natural all-diamond ring


A ring made entirely of natural diamonds has become the first of its type to reach the Gemological Institute of America (GIA) for evaluation.. This is the first example of a solid diamond ring submitted to GIA for identification.

The 13.15-carat, fancy-dark-gray diamond originated from a rough stone weighing about 20 carats, the GIA said in the spring issue of Gems & Gemology journal published last month. It is a type IaB rough diamond recovered in Canada's Northwest Territories.

“While this diamond ring may not be a traditional piece, it carries many unique aspects capturing a snapshot of Earth’s history,” the researchers noted.
