One of the rarest gems in existence, demantoid garnet forms primarily in smaller crystals. First discovered in the Ural Mountains of Russia in the 1860's, demantoid garnet is a variety of garnet that is shaded green in color by trace elements present during the formation of the stone, and has been found in a few other locations since the original discovery in Russia of this rare gem. Until the mid-1990's, demantoid was commonly perceived as a uniquely Russian gemstone, as no other locales produced gem quality demantoid of any commercial importance until Namibia entered the market as a commercially important source.

The immense size of this demantoid, which weighs over five carats, is nearly unheard of in this quality - it is extraordinarily rare. This is one of the largest and finest specimens of demantoid garnet we've had in our collection, as well as being one of the rarest gems we've been privileged to work with.

This gemstone was sourced in Namibia, and the original crystal came from the famed Green Dragon mine. To protect and display this rare gem, we've chosen a platinum mounting of the highest quality and most classic of design. Diamonds with exceptionally fine color and clarity pave the shoulders of this stone, gleaming with bright light, yet set flush to the metal to make a pleasing profile on the finger.
