All diamond rings that we sell set with a diamond of over 1/4 carat (0.25 carat) are accompanied by a Gemological Laboratory Certificate from a diamond laboratory validating the diamond's quality (clarity, cut, color, and carat weight). If you need another opinion on your purchase, we recommend that you take your jewelry item to an independent appraiser during the 30 day time period we provide for returns. The best appraiser is an independent appraiser, i.e., someone who is a member of a recognized appraisal society such as ASA or ISA, who has received formal training in appraisal science, appraises items for insurance and estate purposes, and one who does not sell diamonds or jewelry. It is a good idea to steer clear of jewelers who offer “FREE Verbal Appraisals”. An actual appraisal document is just that, a document which sets a basis for value, most often for insurance replacement purposes in the event of a loss. A verbal appraisal gives the consumer no legal documented proof of the specific details about and detailed description of an item which is absolutely necessary for insurance replacement in the event of theft or loss. Jewelers who give verbal appraisals do NOT have the best interest of the customer in mind.
