Princess, Round, Emerald, Marquis, Pear, Trillion, Heart Shape, Oval, Mine, and any other unusually cut diamonds.

At Blackthorn Estate Buyers & Jewelers, we are interested in evaluating your diamonds with the possibility of purchase. Our diamond buyers are interested in purchasing large stones of at least one carat and are particularly interested in even larger stones. Our experienced gemologist will carefully evaluate your diamond and determine its cut, color, clarity and size. Although a GIA Diamond Certificate is your best assurance of getting what your diamond is worth, we also purchase non-certified diamonds (in any color, whether mounted or not), and jewelry in any condition. If you do not have such a certificate but do have an appraisal or a copy of your sales receipt, please bring a copy with you when you visit us, or scan it and e-mail it to us and our expert diamond buyers will call you to discuss what you have. Please keep in mind that to make a firm offer, it is still necessary to view the stone in person.
