The rarest and most valuable Demantoid comes from Russia, and we only source this Russian Demantoid.
Demantoid is an Andradite, and is a calcium iron silicate with a chemical composition of Ca3Fe2(SiO4)3. It is colored by chromium and tends to be a Pure Vivid Green. It’s impressive brilliance is due to an unusually high refractive index. It’s remarkable light dispersion (the ability to split white light into all the colors of the rainbow) is also unusually high. In fact, Demantoid has a higher dispersion rating, than diamond.
Demantoid was first discovered in the Russian Ural Mountains in 1886, and was named “Demantoid” for its “diamond-like-luster.” It became the favorite of European aristocracy in the late 19th century and it continued to be mined up until the Bolshevik revolution of 1917. Just 25 years ago, Russian Ural Mountain Demantoid mining resumed in 3 locations: Karkodino, Klodovka and Babrovka.

Russian Demantoid is very rare, and a distinguishing feature identifying these gems is known world-wide. Internally the Russian stones display a fine needle pattern that has become known in the trade as a horsetail inclusion. Only the Russian Demantoid displays this unique feature, and so wonderfully. Demantoid is found, but mainly in small sizes, with most stones being under 1 carat. Gems over 2 carats are considered extremely rare, and market prices will acknowledge this.
