We offer a full unconditional 30-day money back guarantee on diamonds.

Simply bring back the diamond and paperwork (paperwork includes the original diamond certificate, where applicable) within the first 30 days of purchasing the item, and you will recieve a full refund. Protea Diamonds has been in business for over forty years. We are listed with the Jewelers Board of Trade and have been voted one of the best places to buy a diamond by Washingtonian magazine four years in a row. By buying a diamond from us we not only offer you a quality product at an outstanding price, we do so with a lifetime upgrade guarantee*. In other words if you buy a stone from us we will credit your original stone purchase (excluding the ring), when you upgrade to a diamond that is double the amount of your original purchase. Bottom line, we sell a quality certified diamond, and back up what we sell with a full thirty-day money back guarantee.

*Please note that this offer excludes special orders.
