The importance of diamond certification
A diamond certificate, also known as a diamond dossier, is a formal document detailing a diamond’s unique characteristics, especially its cut, carat weight, colour and clarity, and may also include its finish (polish and symmetry), fluorescence and additional comments.
The most widely recognised diamond grading laboratories are the GIA (Gemological Institute of America) and EGL (European Gemological Laboratory). Trusted worldwide, these grading laboratories are favoured among the world’s most famous and reputable jewellers.
Certification by a reputable diamond grading laboratory is your assurance of a diamond’s quality and serves as proof of your diamond’s identity. Diamond grading laboratories are completely unbiased in their grading processes. If a diamond is graded by a laboratory, such as the GIA, EGL or SGL, one can be certain that the information stated on the diamond certificate is accurate, and that the diamond will not fall victim to inflated grading.
It is important to understand what each of the different elements on the certificate mean. If you are uncertain about anything, ask the sales executive to explain it to you. When purchasing a certified diamond from Shimansky, you’ll receive the original diamond grading certificate which documents your diamond’s unique characteristics – the 4Cs.
For further peace of mind, a laser inscribed diamond contains a unique diamond identification number on its girdle, matching it to the diamond certificate. This unique identification number, in letters no larger than a few micron, serves two purposes: firstly, to trace the origin of the diamond and secondly, as further security to trace the diamond back to its owner.
When purchasing a diamond from Shimansky, you are guaranteed through your lifetime, that what is stated on your certificate, is what you purchased. All Shimansky diamonds over 0.5ct, and most diamonds of 0.3ct to 0.5ct, are accompanied by a diamond certificate.
