The New York-based GCAL by Sarine lab is now issuing its enhanced 8X Cut Grades certificates for pears and marquise, in addition to round, oval and princess. It introduced the 8X certs in 2021 to provide consumers with "a higher level of transparency" providing what it says is the most comprehensive and stringent assessment of specialty diamond cuts.
Pears, marquise and other fancy shapes are assessed for eight attributes - polish, external symmetry, proportions, optical brilliance, fire, scintillation, optical symmetry and shape aesthetics.
"Creating parameters for cutting 8X Marquise and Pear shapes was more challenging than we anticipated," said Angelo Palmieri, president at GCAL by Sarine. "The 8X standard represents an objective, science-based system that certifies a diamond as "super ideal" across the five shapes we've developed standards for (round, oval, princess and now pear and marquise)."
The lab plans to start issuing 8X certificates for radiant, cushion and emerald cuts as well in the near future.
