How Should A Diamond Certificate Be?

The certificate date and report number are specified in the first part of the certificate, which called the 4C rule; diamond colour, carat (carat), clarity (brilliance), cut especially must be documented among other qualities. There are also organizations that determine the 4C features, which companies evaluate differently within the framework of their own standards, in accordance with international rules. For example, the criteria of leading international rating agencies such as GIA (American Gemology Institute), IGI and HRD Antwerp are valid all over the world.

Organizations that issue international diamond certificates generally carry out their work in laboratories with high technological facilities, serving in line with the special demands of diamond wholesalers or customers. In the laboratories of GIA, IGI, and HRD organizations; The grades of diamonds are determined by examining them with microscopes with 100x and 1000x degrees. In addition to measuring the color and clarity capacities of diamonds with special lenses and advanced microscopes, diamonds are examined by many different gemologists.

IDL (International Diamond Laboratory), headquartered in New York and providing international service, is one of the reliable certification companies of the sector. IDL prepares a large-size diamond certificate (stone book) for diamonds over 1 ct and a small-size diamond certificate for less than 1 ct. In addition to these, jewelery certificates and vacuumed diamond certificates are also within the scope of the certificate services carried out by IDL.

 While the certificates prepared by the brands have an average consistency rate of around 70%, this rate rises to 95% in international diamond certificates. The reason for this is the difference in the development of laboratory facilities. Diamond stone products sold with international certification may be 20% to 30% more expensive than their counterparts. International diamond certification is divided into two categories:

• Stone Certificate (Diamond Certificate): These are the certificates in which the gemstone information is transferred to the document in the most detailed form by examining the diamond before it is processed into jewelry. Even if the gem of the stone is changed, this certificate does not lose its validity.
• Jewelry Certificate: It is the certification of the stone and the jewel as a whole, not separately. In such certificates created after manufacturing, the jewel does not contain all the information about the diamond, as it covers some points of the stone.

What Does a Diamond Certificate Do?

The diamond certificate, above all, proves the quality and originality of the diamond. The information in the certificate should be consulted to determine the value of the diamond; considering that many elements of the diamond can make a difference in price. The diamond certificate obtained from reliable institutions has great importance, in order to prevent errors that may occur while determining the weight, shape, color and clarity of uncertified products.

 Eliminating the trust problem between the seller and the buyer is one of the most important issues in the trade of valuable stones such as diamonds. Diamonds, which are generally considered to be resold in the future by the purchaser, are one of the most depreciated products in the second-hand market. In such cases; it is very important that the product is certified, to minimize possible losses. In addition, a product certificate will help insurance companies to prove the value of the diamond if you encounter cases of theft.
