Certified Diamonds Meaning, DiaEx Explains

A term that often comes up in diamond trade is, certified diamonds – so what exactly does it mean. Diamonds are gorgeous and rare, they are also very expensive. Buyers who spend a lot of money on these glittering stones, would prefer to have some sort of assurance when making a purchase. Diamond testing laboratories fulfill this need, there are at least a dozen well known testing labs across the globe. 

Diamond certification provides critical information related to a specific diamond. The 4C parameters of a diamond have a direct influence on the price of the stone. Color, cut, carat (weight) and clarity need to be accurately defined. The fact is that these parameters have been clearly defined and classified but, sellers are known to inflate the 4Cs of their diamonds. This is done to enable the stone to fetch a better price. 

To begin with, not all diamond testing laboratories are recognized globally. Only a hand full of them have branches across the globe. A diamond certificate would ideally detail the following information related to the stone:

  • The 4C parameters that include color, carat (weight), clarity and cut. 
  • The certificate should clearly state whether the gemstone is natural. 
  • The dimensions of the diamond will also be mentioned on the certificate.
  • Details of the treatment (if any) that has been applied to the diamond. 

The significance of a diamond certificate can be gauged from the fact that, certified diamonds are often traded based solely on the certificate. Buyers need not worry about receiving fake diamonds instead of the real thing. They can also rest assured that, the seller cannot inflate the 4C values for the diamonds being sold. 

There is one additional but optional step involved in the certification of a diamond. The diamond can be microscopically engraved with the number of the diamond certificate. This is generally done on the girdle of the diamond. The engraving is only visible under heavy magnification. This process helps link the diamond to a specific testing certificate. 

Though it might appear that buyers benefit the most from dealing in certified diamonds, the benefits go both ways. Diamond markets in the current scenario seem to have cooled down, one reason is the lack of confidence felt by buyers. When sellers offer their diamonds with a certificate from a reputed testing lab, doubts related to the authenticity of the stones and the overstatement of their 4C values are eliminated. Improved buyer sentiment results in buyers developing a more positive attitude. 

Any discussion on certified diamonds, would not be complete without mentioning synthetic diamonds. Some labs including the internationally renowned GIA, have recently started offering services, for certifying synthetic diamonds. This can be rather confusing and the days when, you could safely presume that all certified diamonds are natural are officially over. The good news is that, diamond testing certificates, make a clear mention about the diamonds being natural or synthetic. Buyers need to carefully check the status of the diamond when reviewing the certificate.
