AGS ASET Scope
ASET technology lets you find out how well, or rather how efficiently, the stone can handle light. There is something called “Angular spectrum”, which is the range of ray angle which can set off the brightness of the stone’s facets. You need to know how to read this information properly and use it as a base for your purchase considerations.
If you find a distinct hearts and arrows pattern, it means the stone is able to show off a profusion of virtual facets, which is good for the sparkle. This also indicates that the stone has been cut to exacting standards, placing it well above the average brilliant cut.
