I definitely want to recommend Blue Diamond Jeweler if you have gold that you are interested in selling. Altaf (the owner) gave me the best price among his competitors. He and his assistant Debbie made the selling process effortless. They were both great to do business with.

Are you interested in consignment?

For clients that would like to sell their jewelry at no urgency, we can maximize the cash value through consignment. We will deep clean your piece so that it can be presented in our showroom displays under the best possible light. You will be informed as soon as your piece has been purchased.
