Facted demantoid garnet with obvious horsetail inclusion sku226 Weight: 0.53 ct Diameter: 5 mm Demantoid is the rarest and most valuable variety of the garnet group. Stones that display the characteristic “horsetail” inclusion — fine fibrous structures of Bissolite — are especially prized by collectors. These inclusions are considered a classic identifying feature of natural Demantoid, particularly those originating from the Ural Mountains. 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...
