When you invest in a beautiful piece of diamond jewellery, it is likely to be an item that you or your loved one will treasure for a lifetime. The jewellery will have a strong emotional value along with the financial value. Therefore, it’s important to know exactly what you are buying, to make sure you are completely happy and have made the right choice.
Diamonds are graded with an international standard, to certify the make up and quality of the gemstone, and provide proof of purchase and information to help appraise, insure, or sell it. A diamond that has been evaluated by a team of gemmologists will be given a certificate, which may be known as the following:
- Diamond Grading Report
- Diamond Dossier
- Diamond Quality Document
A certified diamond will be verified as being either 100% natural, or ‘enhanced.’ An enhanced diamond will typically be of lower value and quality, because it has been treated to disguise cracks, flaws, and true colour intensity. Sometimes enhanced diamonds will not be issued with a certificate.
A diamond certificate will include information about the stone’s shape and dimensions, the carat weight, the colours and clarity grades, and the standard of finish, such as polish or symmetry. In the case of Round Brilliant diamonds, it will also state the cut grade.
For a certificate to be credible, it must be issued by an independent and respected gemmological laboratory, such as the GIA (Gemological Institute of America) or the International Gemmological Institute (IGI), or the Hoge Raad voor Diamant (HRD).
It is not recommended to buy a diamond of 0.30 carat and above without a certificate, because you may not be able to insure it. You will also never be completely sure about the quality of the diamond, so it is worth making this important purchase from a respectable seller who will be able to advise you correctly.
