DIAMOND AND GEMSTONE

Believe that the Diamond 4C rating should be well known by most of consumers. Here we talk about the synthetic diamond or gemstones which are produced in the laboratory (chemical composition or physical properties including hardness are same as the natural diamonds or gems).

Basically, the synthetic diamonds or gemstones cannot be distinguished by naked eyes, they should be only judged by the instrument in the laboratory.


Even though the natural diamond, it could be improved for its clarity or color, through the manual treatment. To improve the color, the heat treatment for gemstones is actually acceptable. However, the brightly colored gems with totally no treatment are more rare in recent years, and more gem customers are specifically looking for them.

For the gemstones with heat treatment, it is difficult to distinguish by the naked eyes too. We shall apply with the color filter, and further judge by the instruments in laboratory.  There will be an indication on the certificate, to show the observation of treatment which is applied to the diamond or the gemstone. Therefore, customer should clearly understand the contents and details in the certificate.
