On average, the retail price for one carat diamonds can be anywhere between $2,000 to $16,000, and between $8,000 to $72,000 for two carat diamonds . And of course, the retail price and the resale value of a diamond are very different things.

A real diamond will reflect light easily, and provide you with a disco ball or rainbow-like display. You can use a flashlight or lamp to do this and it will work best with white light rather than yellow. If the stone absorbs the light, then there's a chance that it's a fake.

If you're serious about finding out whether your diamond is real or fake, you can put the stone through a fire test. Use a lighter to light the stone for approximately 30 seconds, before dropping it in cold water. If it's a real diamond, the stone will remain unharmed, but if it's fake, it will shatter to pieces.
