Also, let us not overlook the open door cost of a gem specialist not having the precious stone in his store available to be purchased for half a month while the reviewing happens.

In 2006, GIA-GTL included a two-dimensional cut reviewing framework for round splendid jewels.
AGS utilizes the strictest cut models in the business. It utilizes a three-dimensional light execution metric that can review a few precious stone shapes. Truth be told, it is the main cut reviewing framework that is perceived by established researchers. Know more details about 鑽石等級
Furthermore, its Diamond Quality Document utilizes an interesting and restrictive 0 to 10 reviewing framework to assess the 4 Cs – a framework which is simpler to fathom than GIA’s evaluating framework.
