Loose 1 Carat Demantoids

One-carat demantoid garnets combine optimal size with exceptional brilliance, making them highly sought after by collectors. Their natural green color and remarkable dispersion (often exceeding that of diamond) create unmatched aesthetic appeal. As conflict-free precious stones, they represent excellent value, with prices reflecting their genuine rarity and the difficulty of sourcing flawless specimens from diminishing Russian and African deposits.

The quality of a loose 1 ct demantoid is primarily determined by its color intensity, clarity, and presence of characteristic “horsetail” inclusions for Russian specimens. High-quality stones display vibrant green hues without excessive darkness. When purchasing natural demantoids, certificates from respected gemological institutes verify authenticity and provide value assurance, though GIA certification is less common than for diamonds due to demantoid’s rarity.

Natural one-carat demantoids make exceptional centerpieces for engagement rings, combining rarity with remarkable brilliance. Their hardness of 6.5-7 on the Mohs scale means they’re durable enough for everyday wear with proper care, though slightly less resilient than sapphires or diamonds. The cost of a high-quality 1 ct demantoid often exceeds that of equivalent-sized diamonds, making them worth considering for couples seeking distinctive, investment-worthy alternatives.

The price of high-quality 1.0 carat demantoids typically ranges from $4,000 to $15,000 per carat, depending on color intensity, clarity, and origin. Russian demantoids generally command premium prices compared to African sources due to their historical prestige and characteristic inclusions. When buying loose demantoids of this size, the cost reflects their increasing scarcity and growing recognition as investment-grade colored gemstones with significant appreciation potential.
