If you have considered buying diamond jewelry like diamond anniversary ring, you may usually face the relevant question: Should you buy certified or non-certified diamonds.
The confusion arises because some experts believe that there is nothing wrong in buying a non-certified diamond. For taking this decision, one can consider the following issues:
• What is the meaning of ‘certified’? In dictionaries, ‘certified means 1) to confirm as accurate or genuine and 2) to ensure it meets a standard.
In case of diamonds, certified means 1) diamond is 100% natural and not enhanced. 2) To ensure its qualities (clarity, color and cut) meet a standard set by an experienced, qualified gemologist.
What is a certified diamond:
A diamond which comes with a grading report from a reputed lab is regarded as certified. The most reputed labs are GIA (Gemological Institute of America), AGS (American Gem Society) and EGL (European Gemological Laboratory). AGS certification is done mostly on near perfect diamonds. But the bulk of certification is done by GIA.
During certification, a diamond is measured as per the color scale, blemishes and inclusions are carefully analyzed and recorded, diamond is weighed in terms of carats and the cut is measured in terms of the diamond’s symmetry, proportions and perfection. Once the grading is done, the diamond receives a certificate which contains details of grading.
A diamond certificate is just a paper. A typical diamond certificate contains information on
Shape and dimension, clarity and color grades, carat weight, standard of finish (symmetry, polish) and cut grade (in round cut diamonds)
When you buy a certified diamond, you also get the certificate which must be kept t in a safe place for future use like insuring, appraising or selling the stone.
What is an enhanced diamond?
An enhanced diamond is a low quality, cheaper diamond which has been subject to major treatment to make it look like an authentic, high quality diamond. Treatments include removal of inclusions by drilling, hiding of small cracks by fracture filling and improving color by color treating. Some diamond labs refuse to certify enhanced diamonds.
Uncertified diamonds: In technical terms, an uncertified diamond is same as a certified diamond except that it does not carry papers conveying grading information. A non-certified diamond ring is not necessarily less quality than one with a certified diamond; it only lacks the relevant grading papers. One can get it graded by sending it to GIA, AGS, or EGL. But the fact is that most certified diamonds cost more than uncertified ones as customers are guaranteed authenticity and quality of diamonds. But if your diamonds are non-certified, there is no need to worry- you can send it easily for grading.
• Self certified diamonds: These are diamonds which have been graded by the retailers themselves.
• Tempting: It is very tempting to purchase uncertified or self certified diamonds for diamond necklaces or wedding diamond rings as they are mostly cheaper than certified stones. But while going in for the big bargain, remember that you may never get what exactly you are looking for and may be stuck with a poor quality diamond.
