This extremely rare Russian Demantoid Garnet is a true gem treasure. It is the most valuable and rarest of the garnet family, more brilliant than both ruby and sapphire, and with the highest dispersion raging (how much light it flashes) of any gemstone - including diamond! This 2.02 carat, beautifully faceted specimen is set in 18k yellow gold and framed in white diamonds. Even a Czarina would be proud to wear this ring.
