Demantoid garnet is one of the rarest and most valuable garnets, known for its vibrant green hue and exceptional brilliance. Its prices vary significantly depending on factors like color, size, clarity, and origin. The most sought-after demantoids have a vivid green color with minimal brown or yellow undertones. Stones with strong “horse-tail” inclusions, a unique feature, are especially prized.

Prices for high-quality demantoid garnets can range from $1,000 to $10,000 per carat or more. Smaller, lower-quality stones with duller colors or visible inclusions typically cost much less, ranging from $200 to $500 per carat. Larger stones over one carat are rare and command premium prices, especially if they display intense color and excellent clarity.

Demantoids from Russia, especially the Ural Mountains, are considered the most valuable due to their rich history and superior quality. However, high-quality stones from newly discovered in Pakistan, Namibia and Madagascar are also well-regarded. Collectors and jewelry enthusiasts are drawn to demantoid garnets for their beauty and rarity, making them a coveted gemstone in the market.
