GLIS-3000 is a desktop diamond verification instrument for loose and mounted diamonds, designed to separate natural diamonds from synthetic diamonds. GLIS-3000 is manually operated and requires the user to interpret the test results.
The performance metrics shown below are based on testing done in 2019 using the ASSURE 1.0 test standard and sample sets. The GLIS-3000 has not been tested under ASSURE 2.0.
Weight: All
Size: All
Colour: D-J
Shape: All
Diamond Simulants: No
Mounted Stones: Yes (not yet ASSURE Tested)
The below results demonstrate the performance of the GLIS-3000 when tested by an Expert Operator
Core Sample
Diamond False Positive Rate (optimal rate 0%): 16.1%
Diamond Referral Rate (optimal rate 0%): 0.6%
Diamond Accuracy Rate (optimal rate 100%): 95.3%
Speed (stones tested per hour): 1,183
The ASSURE 1.0 Core Sample consists of 1,000 loose diamonds, 200 loose synthetic diamonds and 200 loose diamond simulants if applicable. The stones are 0.02ct to 0.20ct in D-J colour.
Smalls Sample
Diamond False Positive Rate (optimal rate 0%): 3.7%
Diamond Referral Rate (optimal rate 0%): 0.0%
Diamond Accuracy Rate (optimal rate 100%): 93.3%
Speed (stones tested per hour): 1,183
The ASSURE 1.0 Smalls Sample consists of 1,000 loose diamonds, 200 loose synthetic diamonds and 200 loose diamond simulants if applicable. The stones are 0.005 ct to 0.02 ct in D-J colour.
Automated Feed: No
Automated Results: No
Automated Dispense: No
Detect or Refer (Synthetic Diamonds): Refer
Detect or Refer (Diamond Simulants): N/A
Multiple Stones at Once: Yes
Training Required: Yes
GLIS-3000 captures multiple images and based on visual analysis of the images, and support from a decision tool, the operator concludes the nature of the stones. The following results can be concluded by the operator based on the data generated by the GLIS-3000:
‘Refer’ could indicate potential synthetic diamonds and diamonds. The referrals should be tested further for full verification.
