Demantoid is one of the rarest and most valuable varieties of garnet, admired for its vivid green hues and exceptional brilliance. Its fiery dispersion, often greater than that of a diamond, gives it unmatched sparkle, making it one of the most sought-after collector’s gemstones. The finest demantoids display an intense green with flashes of golden fire, while some even contain delicate “horsetail” inclusions, unique to stones from Russia, which add to their rarity and desirability.
With a hardness of 6.5–7 on the Mohs scale, demantoid is durable enough for jewellery while remaining a rare and treasured gem. Symbolically, it is associated with prosperity, vitality, and regeneration, making it a meaningful choice for jewellery and investment alike.
Each demantoid is unique, with colour, clarity, and inclusions determining its value. Historically sourced from Russia’s Ural Mountains, demantoids are also found in Namibia and Madagascar today, though the Russian stones with horsetail inclusions remain the most prized.
