Gem Certification & Assurance Lab (GCAL), and Sarine Technologies, have teamed up to form a new partnership in 2023, GCAL by Sarine brand.
This new partnership combines GCAL’s uncompromising standards, backed by its industry-unique 4C’s consumer guarantee, and Sarine’s revolutionary AI based Color and Grading Technology to transform the diamond industry.
Carat is a weight unit used to measure diamonds and gemstones. It was formally adopted in 1907 at the Fourth General Conference on Weights & Measures in France, and spread as the internationally recognized standard. Carat weight is a unit of mass equivalent to 0.2 grams. A 1 carat diamond weighs 0.2 grams (200 milligrams). Diamond pricing is affected by all 4Cs, so a smaller diamond of higher Clarity and Color, or a small superbly cut diamond, may be priced higher than a larger, lesser quality diamond.
Cut grading was revolutionized in 1992 with the market introduction of Sarine’s DiaMension®. It was the first software in the world to provide automated and computerized measurement of the diamond’s proportions – the most critical aspect affecting Cut grade. DiaMension® transformed how polished diamonds are assigned their Cut grade, enabling unparalleled levels of accuracy.
In white diamonds, minor color differences, which are often imperceptible to the naked eye, can make a big difference in determining a diamond’s value or demand in the retail market. The way to overcome this is via the use of standardized reliable AI-based color grading that demonstrates consistent accuracy rates that surpass those achieved via manual color grading.
Sarine Clarity™ enables automated mapping of diamond inclusions and blemishes, that overcomes the inconsistencies of subjective human perception. Automated clarity grading enables diamond producers to sort diamonds into sub-categories according to pre-defined clarity grading criteria, so each diamond can be targeted to its ideal sales market.
A diamond’s light performance is a measure of its interaction with light. Light performance is the most accurate and comprehensive way to determine a diamond’s visual appeal, and also its uniqueness – as no two diamonds have the same light return. Not only a descriptor of its beauty, did you know diamonds with high light performance grade can command a higher retail price? We talk about a diamond’s light performance using terms such as fire, sparkle, scintillation, and symmetry.
