A diamond’s certification is the official documentation that details the gemstones authenticity and quality; think of it as the birth certificate for your stone. A diamond certificate (also referred to as a diamond grading report, diamond dossier, or diamond quality document) is issued following an examination of a diamond’s attributes including its carat weight, colour, clarity, symmetry, polish and exact measurements by a team of professional gemmologists. A cut grade is also usually provided for most round diamonds.
During the examination each diamond is individually scrutinised and evaluated to clarify the true value and integrity of the diamond. It’s important to request a certificate when buying a diamond to avoid purchasing an item of lesser quality than advertised and it helps to provide peace of mind in knowing what you are buying. It also helps to determine an accurate insurance figure and it’s a valuable tool when comparing and buying items at a fair price. The most prominent, internationally recognised certificates that we recommend are those issued by the GIA and HRD.
All of the diamonds over a carat weight of 0.30cts used in the jewellery pieces we create and that are sold through our Woollahra boutique can be accompanied by a GIA certificate upon request. With diamonds of a smaller carat size the value of the diamond often rivals the cost of the certification and does not warrant a certificate.
