Demantoid

Demantoid Garnet is one of the rarest and most coveted gemstones in the world, prized for its electric green fire and the famous "horsetail" inclusions that betray its Russian origin and are uniquely treasured rather than considered flaws. First discovered in the Ural Mountains in the mid-19th century, it became a favorite of the Russian imperial court and the great jeweler Fabergé, who set it into some of the most legendary pieces of the era. A member of the andradite garnet family, Demantoid carries a dispersion higher than diamond's — hence its name, from the Dutch demant, "diamond-like" — giving it an unmistakable sparkle that flashes rainbow flares in the light. At 0.98 ct, this stone is a serious collector's size for a species where any reasonably clean piece over a carat is genuinely scarce. Compact, untreated, and brilliant beyond its weight class, it brings quiet rarity and unmistakable presence to any setting.
