At Diamond Wish we provide a free appraisal report along with every item. All our jewelry is shipped with a Certificate of Authenticity that certifies quality and that the final product is as described on the website and as promised to you. All our diamonds are 100% natural. Upon special request,we can also provide a free appraisal of item value for insurance purposes. The appraisal document states the approximate retail value of the item including details about the diamond cut, color, clarity, and either carat weight for diamonds or dimensions of gemstones, and the craftsmanship of the item.
