Instrument Performance

The below results demonstrate the performance of the GLIS-Mini when tested by an Expert Operator.

Core Sample

Diamond False Positive Rate (optimal rate 0%): 11.1%
Diamond Referral Rate (optimal rate 0%): 0.8%
Diamond Accuracy Rate (optimal rate 100%): 93.2%
Speed (stones tested per hour): 951

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%): 7.3%
Diamond Referral Rate (optimal rate 0%): 16.4%
Diamond Accuracy Rate (optimal rate 100%): 80.1%
Speed (stones tested per hour): 951

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.

Instrument Capabilities

Automated Feed: No
Automated Results: No
Automated Dispense: No
Detect or Refer (Synthetic Diamonds): Detect
Detect or Refer (Diamond Simulants): Refer
Multiple Stones at Once: Yes
Training Required: Yes

GLIS-MINI 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-MINI:

1. Pass – natural diamond
2. Refer

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