Instrument Performance

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 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.

Small 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 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.

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:

1. Natural type Ia diamond
2. HPHT synthetic diamond
3. Refer

‘Refer’ could indicate potential synthetic diamonds and diamonds. The referrals should be tested further for full verification.
