(IDEX Online) - Diamond tech firm Sarine has joined forces with the National Gemstone Testing Center (NGTC) in China to offer "light performance" grading reports.

They go beyond the 4Cs and measure brilliance, sparkle, fire and light symmetry, on a scale for inimum to exceptional, resulting in an overall light performance grade. 

The collaboration combines Sarine's development in AI-based grading for the 4Cs and light performance with NGTC's extensive gemological research and diamond testing expertise.

Sarine Technologies, based in Israel, entered into a strategic agreement with NGTC in September 2019.

They will provide co-branded authentication reports in the first instance for the Rose D′Amour brand by Yuanyumei (Y & M) Jewelry, a leading high-end Chinese jewelry brand.

Mr ZhiBin Ye, president of NGTC, said: "Consumers will experience the benefits of diamond light performance testing technology for more confident and safer buying."...

(IDEX Online) - Alrosa says it will again offer buyers zero buyouts and extra flexibility at its rough trading session later this month.

It says it is aiming to "nurture the green shoots of market recovery," after August sales leapt to $217m, from a monthly average of just $30m during the depths of the pandemic.

The Russian miner acknowledged that the market has yet to reach a balance and there was still the risk a new wave of the disease, but said there had been evidence of renewed demand in recent weeks.

"During the last month we clearly see the growing demand for rough diamonds as cutting and polishing factories in India are ramping up and revived Chinese jewelry sales' dynamics is encouraging," said deputy CEO Evgeny Agureev. 

"On the other hand, there is still an uncertainty related to the risk of the new wave of counter-COVID restrictions as well as to consumer sentiment. 

"This is why we would be able to talk about the full-scale market recovery only based on the results of the key holiday season in the USA."

Alrosa's trading session is from September 21 to 25 at its offices and remotely online
