DiamondSure is a portable desktop diamond verification instrument for loose and mounted stones, designed to separate diamonds from synthetic diamonds. DiamondSure is manually operated but gives an automatic test result.
The performance metrics shown below are based on testing done in 2019 using the ASSURE 1.0 test standard and sample sets. More recent test results for DiamondSure can be found here in the ASSURE 2.0 Directory.
Weight: 0.05 ct-10 ct
Colour: D-J (failsafe across all colours although natural fancy colours will give a higher referral rate)
Shape: All
Diamond Simulants: Yes (not ASSURE Tested)
Mounted Stones: Yes (not yet ASSURE Tested)
The below results demonstrate the performance of the DiamondSure with the ASSURE 2.0 Core Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 4.7%
Diamond Accuracy Rate (optimal rate 100%): 95.3%
Speed (stones tested per hour): 193
The ASSURE 2.0 Core Sample consists of 1,000 loose diamonds, 200 loose synthetic diamonds and 200 loose diamond simulants. The stones are 0.02ct to 0.20ct in D-J colour.
Automated Feed: No
Automated Results: Yes
Automated Dispense: No
Detect or Refer (Synthetic Diamonds): Refer
Detect or Refer (Diamond Simulants): N/A
Multiple Stones at Once: No
Training Required: No
The instrument tests individual stones and automatically displays one of the following results:
The ‘Refer’ results could contain potential synthetic diamonds, diamond simulants and diamonds. These referrals should be tested further for full verification.
