They improved on this in 2005 with the introduction in ใบเซอร์เพชร the sector’s to start with scientifically reviewed and diamond-specific efficiency metric. They are really certainly one of two best-tier laboratories offering Minimize high-quality and general performance assessments for specified fancy shapes.

By ใบเซอร์เพชร way of example, a diamond’s clarity is graded by looking on the stone below 10x magnification to find out the number, visibility, and situation of any detectable flaws Which might be existing while in the diamond.

Concentrating on cut excellent, the AGS certification aids purchasers grasp the legitimate splendor and value of their diamonds.
