DiamondView by De Beers Group Industry Services

Instrument Description

DiamondView is a desktop diamond verification instrument for loose and some mounted stones. DiamondView is designed to authenticate diamonds and synthetic diamonds. DiamondView is manually operated and requires an operator to interpret the test results. DiamondView is suitable for an environment where experienced technicians are present e.g. gemmological laboratories, large diamond manufacturers and retailers with in-house testing facilities. DiamondView is typically used as a means of examining referral diamonds, but the instrument can be used independently as well. ASSURE ID: 217964.

How Does it Operate?

The user manually places the loose or mounted stones inside the test chamber of the instrument. To start the testing, the user closes the test chamber and starts the testing software. DiamondView displays images and based on visual analysis the operator concludes the nature of the stones.

 

The following results can be concluded by the operator based on the data generated by the DiamondView:

 

  1. ‘Diamond’
  2. ‘Synthetic diamond’

 

In the majority of cases an experienced user can judge whether the stone under test is a natural or synthetic diamond.  In very few cases additional measurements may need to be carried out.

 

ASSURE Test

DiamondView 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. DiamondView requires manual interpretation and the instrument was tested both with a novice and a manufacturer appointed expert. The manufacturer appointed an expert from UL’s team. 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. DiamondView was tested with the ASSURE Core Sample.

 

The summary test report issued by UL 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 0%
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 diamonds to the total number of diamonds 100%
Speed Stones tested per hour 112
Synthetic Diamond Accuracy Ratio of synthetic diamonds correctly classified as synthetic diamonds to the total number of synthetic diamonds 100%
