The Assure 2.0 website evaluates and contrasts the many verification devices on the market, taking into account the sorts of diamonds it screens for, the amount of diamonds it can process, the size of the device, and the level of skill necessary. A third-party laboratory independently tests each diamond against an Assure sample, which includes natural and lab-grown diamonds as well as simulants. According to the NDC, the sample contains synthetic diamonds that are not yet commercially available in the industry. They are graded based on the number of false positives (how many synthetics or simulants are mistakenly flagged as naturals), the number of referrals (how many need to be "referred" for further testing), and overall accuracy.
The optimum false positive and referral rates, according to the NDC, are zero, while the optimal accuracy rate is 100%. According to the NDC, all instruments are operated by a beginner to imitate the results expected from a new customer of the item. Participants in the programme can display the Assure Partners and Certification Mark, which indicates that the programme has been independently assessed. According to the NDC, the mark is not an endorsement of the device or its test findings. The announcement comes as De Beers introduces yet another new diamond screener: an automated melee device that can screen up to 3,600 small diamonds per hour to determine whether they are natural or lab-grown.
According to a spokesman for JCK, the machine "particularly caters to the tiniest melee sizes, from 0.0033 carats down to 0.001 carats—one-tenth of a point." "By using an automated technique, it considerably improves the efficiency of the procedure for screening diamonds of this size." According to the company, the machine was created in collaboration with the industry and "needs no additional displays or further equipment and runs as a totally standalone unit." The innovative gadget, which took De Beers Group Ignite 18 months to build, will be ready in 2023. The price has not been disclosed.
