ASSURE Test

D-Secure+ was tested in accordance with the Diamond Verification Instrument Standard with the test protocol for instruments that separate diamonds from synthetic diamonds (Operation Category 1).

 

The tests took place at the independent laboratory UL in Canton, Massachusetts, United States.

 

D-Secure+ provides semi-automatic interpretation and the instrument was tested both with a novice and a manufacturer appointed expert. The manufacturer appointed an expert from DRC Techno. The below results are from the expert tests. Both the novice and the expert test results can be found in the summary report issued by UL. D-Secure+ was tested with the ASSURE Core Sample and ASSURE Smalls Sample.

 

The UL test report including more detailed test results can be found here.

 


ASSURE Core Sample

The ASSURE Core Sample consists of 1,000 loose diamonds and 200 loose synthetic diamonds. The stones are 0.02 ct to 0.20 ct in D-J colour. The below results are from the test with the ASSURE Core Sample.

 

Diamond False Positive Rate Ratio of synthetic diamonds incorrectly classified as 'diamond' to the total number of synthetic diamonds 14.1%
Diamond Referral Rate Ratio of diamonds being referred for further testing to the total number of diamonds n/a
Diamond Accuracy Ratio of diamonds correctly classified as ‘diamond’ to the total number of diamonds 94.7%
Synthetic Diamond Referral Rate Ratio of synthetic diamonds being referred for further testing to the total number of synthetic diamonds n/a
Speed Stones tested per hour 948
ASSURE Smalls Sample

The ASSURE Smalls Sample consists of 1,000 loose diamonds, 200 loose synthetic diamonds and 200 loose diamond simulants. The stones are 0.005 ct to 0.02 ct in D-J colour. The below results are from the test with the ASSURE Smalls Sample.
