GCAL Expands 8X Cut Grade to Fancy Diamond Shapes
It will introduce the 8X Oval and 8X Princess Diamond Cut Grade certificates at the upcoming JCK Las Vegas jewelry trade show.
The new cut grade from GCAL considers eight critical factors: polish, external symmetry, proportions, optical brilliance, fire, scintillation, optical symmetry, and shape aesthetics.
Angelo Palmieri, GCAL COO and partner, said the lab has a “vast wealth of analytical images and data” from all the stones that have passed through it since it opened in 2000, including millions of photomicrographs, direct assessment images of optical brilliance, optical symmetry, scintillation, fire, and measurements.
The cut grade can be used for both natural diamonds and lab-grown diamonds.
