Diamond certificates can be invaluable documents showing in detail a diamond's credentials. They provide a unique fingerprint of a diamond which is a source of vital information to the trained gemologist, jeweller and consumer.
A diamond certificate will contain a complete description of the diamond and will include information on shape, weight, clarity, fluorescence, colour grade, measurements, proportions and the finish grade. It will also confirm that the stone is indeed the genuine article.
A diamond certificate, however, is only useful if it is reliable and has been issued by a reputable independant laboratory which has no financial interest in the stone. If you've never heard of the institution that is offering a grading report, don't hesitate to ask about its credentials.
One important thing to remember is that a grading report does not include an appraisal, or any kind of statement about the monetary value of the diamond. It is an opinion on what they feel is the real grading of that stone. Thus, a Diamond Certificate is not to be confused with a Valuation Certificate.
A Diamond Certificate, from a recognized Gem Trade Laboratory, is like a unique ID card for a diamond. It not only identifies the diamond but also provides important information which helps both consumers and jewellers alike.
Be fully aware of jewelers that try and sell you diamonds with their own grading certificate of a stone. They are selling it for their interests and not yours. Here you will find a list of reputable laboratories that are independent and have no financial interest in the stones.
