The ASSURE Program, a joint collaboration between the Diamond Producers Association (DPA) and Signet Jewelers, has developed a universal standard to test the performance of Diamond Verification Instruments in a consistent way, with the aim of protecting the integrity of the global jewelry supply chain. The instruments are rigorously tested in a transparent manner against a unique common sample and standard.
The ASSURE Program partnered with 11 manufacturers representing the 18 most widely available Diamond Verification Instruments in the market. These instruments were submitted for testing to third-party laboratory UL and a Technical Committee comprising leading scientists and academics from major gemological organisations.
Adequate detection and screen processes using Diamond Verification Instruments are one of the key tools in safeguarding operations from undisclosed laboratory-grown diamonds . Through the ASSURE directory, trade participants can access objectives and learn about how to ensure pipeline integrity using Diamond Verification Instruments.
Each instrument is tested on the ASSURE Core Sample, a highly contaminated sample made up of 1,000 mined diamonds and 200 laboratory-grown diamonds including very challenging laboratory-grown diamonds, some of which are not yet available in the market.
Screen-I is a portable diamond verification instrument for loose and mounted diamonds. Screen-I is designed to separate natural diamonds from synthetic diamonds. Screen-I is manually operated but gives an automatic test result. Screen-I is suitable for an environment where you need to test both loose and mounted diamonds e.g. retailers, manufacturers, pawnbrokers, appraisers, gemmologist and hobbyists.
