F.A.Q's

How can I pay you?

Is there a shipping charge?

OnDiamonds.com offers FREE, safe, guaranteed shipping for any domestic purchase using FedEx. To learn more about shipping, see our Shipping Policy.

Am I getting a fair price?

We believe we offer you the best price and excellent value. Thanks to the Internet, you can research diamonds on different Web sites to determine the best value for your needs. Of course, you need to compare exactly similar stones in size, shape, clarity, color and measurements because even a small difference causes a large price difference.

Why is my credit card being rejected?

The most likely cause of rejection is a mismatch in the card type and number (entering Visa for the card type and then entering a Mastercard number), or mistyping your credit card number on the form. If you still have trouble, please call 888-5-ONDIAMOND (888-566-3426) between 9am to 7pm EST, M-F.
