A market-wide average across qualities and sizes. Your stone's value depends on carat, color, clarity, cut, treatment, and origin.
Cuprite is a copper oxide mineral that, in rare transparent form, can produce gemstones with a rich, deep red color and exceptional luster. However, with Mohs hardness around 3.5–4 and very high density and brittleness, it is fragile and best suited to collection pieces rather than everyday wear.

The GemstoneAI market index for cuprite is $96 per carat as of 2026-08-04. That is a market-wide average across qualities, not a quote for a specific stone. Individual value depends on carat, color, clarity, cut, treatment, and origin.
Visual tests alone are unreliable. GemstoneAI analyzes a photo of your stone for identity, treatment indicators, and authenticity signals, then estimates market value. It is free to try.
Over the past 30 days the cuprite index moved +0.4%. Gem prices move on supply, demand, and metal markets; treat any single stone as a collectible first and an asset second.
