As a direct reflection of the brilliance of diamonds, Sarine Optical Performance Certificate clearly describes the diamond's ability to respond to light from four dimensions: brightness, luster, optical symmetry and brilliance.
In fact, many jewelry brands in Chinese mainland are equipped with this certificate, such as TIAMIUG Zhi Zhi jewelry, my queen Man Kun, JAFF jewelry and so on. I won't go into details here. The subject can go to the diamond ring shop to find out if it is equipped. It is worth mentioning that NGTC cooperated with Sarine to launch the [Rose Seal] series jewelry with a certificate of honor. It is said that it will be available soon, so you can look forward to it.
