SYNTHdetect by De Beers Group Industry Services
SYNTHdetect is a desktop diamond verification instrument for loose and mounted stones. SYNTHdetect is designed to separate diamonds from synthetic diamonds and diamond simulants. SYNTHdetect is manually operated and requires an operator to interpret the test results. SYNTHdetect is suitable for an environment where you need to test both mounted and loose diamonds e.g. dealers, diamond and jewellery manufacturers, retailers, buyers and gemmological laboratories.

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.
SYNTHdetect captures images and based on visual analysis of the images the instrument automatically presents the results that can be interpreted by the operator.
SYNTHdetect displays one of the following results:
The ‘Refer’ result could contain potential synthetic diamonds, diamonds and diamond simulants. These referrals shall be tested further for full verification. De Beers Group Industry Services recommends further testing with the DiamondView or by a gemmological laboratory.
The instrument does require user interpretation although it contains the software to aid in this interpretation. The instrument might also require some adjustments by the user to obtain the best image.
SYNTHdetect needs to be calibrated periodically to ensure continued high performance. The user will be notified by the software when the calibration needs to be carried out. A calibration sample is supplied with the instrument.
What are the Performance Test Results?
SYNTHdetect was tested in accordance with the Diamond Verification Instrument Standard with the test protocol for instruments that separate diamonds from synthetic diamonds and diamond simulants (Operation Category 2).
The tests took place at the independent laboratory UL in Canton, Massachusetts, United States.
SynthDetect was tested with the ASSURE Core Sample that consists of 1,000 diamonds, 200 synthetic diamonds and 200 diamond simulants. 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.
SYNTHdetect requires manual interpretation and the instrument was tested both with a novice and a manufacturer appointed expert. The manufacturer appointed an expert from De Beers Group Industry Services. 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. Please note that the novice results were obtained after in-person training of the novice that operated the instrument; which is something that needs to be borne in mind to obtain these levels of results.
The summary test report issued by UL can be found here.
|Diamond False Positive Rate||Ratio of synthetic diamonds (and diamond simulants) incorrectly classified as 'diamond' to the total number of synthetic diamonds (and diamond simulants)||0%|
|Diamond Referral Rate||Ratio of diamonds being referred for further testing to the total number of diamonds||0.7%|
|Diamond Accuracy||Ratio of diamonds correctly classified as diamonds to the total number of diamonds||99.3%|
|Speed||Stones tested per hour||TBD|
|Synthetic Diamond Referral Rate||Ratio of synthetic diamonds being referred for further testing to the total number of synthetic diamonds||100%|
