How much would a 2.1 CT diamond ring cost?

The money you pay for a diamond depends on its cut, clarity, carat weight and colour. You can spend several hundred dollars or several million dollars for a diamond.

Today, on Blue Nile, you can buy a diamond of this carat weight and spend between US$9,200+ and US$47,000+, depending on the clarity, colour and cut that you want.

Then you'll pay in addition for the ring mounting and the jeweler's time to mount the diamond in the ring that you've chosen.
