Frequently Asked Questions (FAQs)

1. Are rough diamonds worth anything?

Pros: They cost way less. The biggest appeal of purchasing a rough diamond is that they are often less expensive than cut diamonds. You can find an uncut, 1-carat diamond ring for a few hundred dollars vs a few thousand for the same sized cut ring.

2. Are rough diamonds cheaper?

Simply put, rough diamonds are cheaper than their more polished counterparts, mostly because they haven't undergone an expensive cutting and polishing process. This doesn't mean they are any less spectacular; in fact, as we've said, their beauty lies in their natural and unpolished look.

3. How much is a 1 carat uncut diamond worth?

The price of a 1 carat diamond is between $1,300 and $16,500, depending on factors such as the diamond's cut quality, clarity, color and shape.

4. How do you identify a rough diamond?

Put the diamond under the loupe or microscope and look for rounded edges that have tiny indented triangles. Cubic diamonds, on the other hand, will have parallelograms or rotated squares. A real raw diamond should also appear like it has a coat of vaseline over it. Cut diamonds will have sharp edges.
