Your diamond is a valuable investment, therefore it's important that your diamond includes a certificate from a reputable gemological lab. A diamond certification is an assurance of quality and summarises the specification and value of your diamond such as the carat, cut, clarity and colour.
Keep your diamond certificate in a safe place, in case you need it for insurance purposes if your diamond is lost or stolen, or to confirm its value for re-sale.
Not all labs are created equal, and many labs have relaxed their gradings, allowing lower quality diamonds to be represented at a higher value in the marketplace.
All Alan Weiss diamonds are certified by the Gemological Institute of America or the International Gemological Institute.
