What is the price of 10 carat diamond?

The value of a diamond depends on its cut, its clarity, its colour and its carat weight.

You can buy a round, fairly high-quality stone today on Blue Nile in the 10-carat range (8 carat or 12 carat) and spend US$1.1 or US$1.2 million.

A local jeweler may be able to show you the stone you want to buy.

If you have a diamond of this size and want to sell it, best practices dictate that you pay for a certified gemologist to document the diamond's characteristics. This will help you establish a price for your diamond.
