Faceted demantoid garnet sku229 Weight: 0.5 ct Diameter: 5.2 mm Demantoid is the rarest and most valuable variety of the garnet group.

Rather than reducing value, a well-formed horsetail inclusion is often seen as confirmation of authenticity and a distinctive natural characteristic of this gemstone. This demantoid originates from the historic Bobrovka deposit in the Ural Mountains, Russia, one of the most famous sources of demantoid garnet in the world. Uralian demantoids have been prized since the 19th century and were particularly popular in Russian Imperial jewelry...
