The Belgian High Class Diamond Council (HRD) plans to issue a synthetic diamond certificate service on September 2 to prevent the discovery of synthetic diamonds in the future. The Parliament pointed out that recently synthetic diamonds have entered the gem diamond market. In addition, the Belgian High Class Diamond Council Gemological Laboratory stated that although synthetic diamonds are now only a small part of the market, their production is constantly rising.
Therefore, the Belgian high-level diamond council said: "In order to support consumer confidence, they are ready to launch a new service."
According to the International Diamond Council regulations, the Belgian high-level diamond council certificate is clearly different from the standard diamond certificate, and the certificate has a clear text 'synthetic diamond certificate' on the cover. Each synthetic diamond is laser engraved, and laser engraving is also mentioned in the certificate to show that the diamond was cultivated in the laboratory.
In addition, each synthetic diamond certificate includes the same unique safety features as the Belgian High Class Diamond Council Natural Diamond Certificate.
The Belgian High Class Diamond Council also provides screening services for high temperature and high pressure (HPHT) and chemical vapor deposition (CVD) synthetic diamonds. This service is intended to help diamond dealers ensure that each diamond packaged product is natural.
This inspection includes a minimum of 20 diamond packages ranging in size from 0.05-0.49 carats and colors from D to L. After the package is filtered, the customer receives a sealed postal packet with a filtered report with a caption. The package contains only natural diamonds, not artificial and high temperature and high pressure.

Medium and Trace elements are necessary for plant growth, but relatively small amounts of elements, mainly CaO, iron, copper, zinc, manganese, molybdenum, boron and so on. Trace elements are small in the body of the crop, but because they are often part of the enzyme or coenzyme within the plant, they are highly specific and are indispensable and irreplaceable for crop growth and development.
