New synthetic material on the gems market

Author:, Published:


Swiss gemological laboratory Gemresearch Swisslab reported a new synthetic material, which is marketed as a natural and is sold at very high prices – thousands US dollars per piece or sometimes per carat. The material is light colored (beige) and mimicked a naturally weathered product. It is characterized by a specific gravity 3.53, green phosphorescence when exposed to a strong light source and patchy blue to green fluorescence  in UV-light (short- and long wave).

The material has been studied in Gemresearch Swisslab laboratory. More on this subject can be found here.
