Diamond company Sarine unveils technology to more accurately grade color and clarity


Diamonds are typically graded based on the so-called 4 C’s: color, clarity, cut, and carat (weight). Color diamonds tend to fetch a higher price than clear ones, but judging their color is still largely a human endeavor, the same with hunting for imperfections that might ruin the pure clarity of a stone. That’s where Sarine’s new “Sarine Clarity” and “Sarine Color” solutions are hoping to make a massive difference.

“Technological standardization translates into greater credibility for the industry and increased trust for the diamond consumer,” Sarine CEO Uzi Levami said in a press statement. The two new solutions join the company’s DiaMension system that measure the cut of polished diamonds.

Sarine — which is a public company traded on the Singapore Exchange Mainboard — held a press conference in Israel’s diamond district, nestled in Tel Aviv’s sister city of Ramat Gan. The Color and Clarity solutions are being tested with polished diamonds right now in India, another hub of the global diamond industry. Their software maps flaws and “inclusions,” which together are generally referred to as “birthmarks” in the industry. Based on the grades, diamonds will be sorted into subcategories, allowing for better valuation based on industry standards for polished diamonds.

Sarine Clarity has some limits apparently, as it only works on rocks that are between 2 and 10 carats, though the reason for that might be more practical. Stones larger than that tend to be extremely valuable and sold at auction, where the practice would be to have it checked over by hand anyways. Where this tech will have a chance to sparkle and shine is in dealing with the more average size and smaller rocks that make up far more of the industry, and consume the vast majority of time from appraisers.

Color can only be graded on stones weighing 20 points and up (a point being 1/100 of a carat, a stone must be at least a fifth of a carat in weight to work with the system).

Diamonds are no longer just the realm of established companies in the industry, but also several startups. London-based Everledger produces a fraud detection system based on blockchain to trace diamonds which utilizes big data from insurers and law enforcement agencies to prove authentic ownership, something that’s gained them a lot of notoriety.
