Step 1 of 3: How can we help?

How can we help?

We tailor your valuation based on whether you're buying or selling.

Independent pricing data. We don't buy or sell gemstones, we just show you what the market says.

About GEMIUS Valuation›

GEMIUS gives you an independent market price range for a colored gemstone. Choose the species, enter the carat weight and describe the quality attributes you can see, and the tool returns a range in seconds. It is free and it needs no account.

We do not buy or sell gemstones. We are not a marketplace and we take no commission on a stone, so the range is not shaped by anyone wanting to be on one side of the trade. It is independent pricing data showing what the market says.

Two stones of the same species and the same carat weight can be worth very different amounts. Colour, clarity, cut and origin all move the figure, so the answer is a range rather than a single number that would hide that spread.

The tool prices 23 species. Each links to its reference page.
