We provide a diamond "certificate" report from the Gemological Institute of America or the European Gemological Laboratory with all loose diamonds and diamond rings set with a diamond of over 1/4 carat (0.25 carat) because we want our customers to feel secure about the diamond they are purchasing before, during and after their important diamond purchase. You can shop at the Antique Jewelry Mall with confidence knowing that not only do we guarantee what we sell to be exactly as described, but that your included Diamond Laboratory Report from an internationally respected independent laboratory affirms the value and quality of your diamond. Also of added benefit to you is the fact that a diamond with a certificate is easier to insure, and more straight forward for an insurance company to replace with an item of equal value and quality in the unfortunate event of a loss. Diamonds and diamond rings which include a Diamond Report ( Certificate ) at time of purchase will clearly note this fact in the item description.
