Frequently Asked Questions (FAQs)

1. Are loose diamonds worth anything?

The value of loose diamonds does not depend on their age, assuming that they are in good condition. The market value of any loose diamond will depend on the famous “4 C's”—cut, color, carat and clarity. If you purchased the diamond, you probably know its ranking.

2. Are cut diamonds worth more?

They are priced based on the same 4Cs as modern diamonds, but because their quality tends to be on the lower end of the scale (a lot of the higher color/clarity stones have been recut to reflect today's standards), they're usually more affordable.

3. Can a jeweler set a loose diamond?

Both online jewelers and diamond wholesalers that sell loose diamonds will set your diamond for you in a variety of different ring styles. If you want a setting that's highly-customized, there are many independent jewelers that will be happy to set your ring in a custom design.

4. How much does cutting a diamond cost?

Diamond cutting professionals can be very expensive. Cutting is usually priced per carat, so expect to pay anywhere from $125 to $400 per carat! And remember, there are no guarantees. If you picked a low-quality stone to begin with, all of your effort will be fruitless.
