SYNTHdetect

SYNTHdetect

SYNTHdetect is a desktop diamond verification instrument for loose and mounted stones. It is designed to separate diamonds from synthetic diamonds and diamond simulants. SYNTHdetect is manually operated and requires an operator to interpret the test results.

The performance metrics shown below are based on testing done in 2019 using the ASSURE 1.0 test standard and sample sets. More recent test results for SYNTHdetect can be found  in the ASSURE 2.0 Directory.

Stone Testing Capability

Weight: 0.001 ct-100 ct
Colour: D-J (failsafe across all colours although natural fancy colours will give a higher referral rate)
Shape: All
Diamond Simulants: Yes
Mounted Stones: Yes (not yet ASSURE Tested)

Instrument Performance

The below results demonstrate the performance of the SYNTHdetect with the ASSURE 1.0  Core Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 0.7%
Diamond Accuracy Rate (optimal rate 100%): 99.3%
Speed (stones tested per hour): 583

The Core Sample consists of 1,000 loose diamonds, 200 loose synthetic diamonds and 200 loose diamond simulants. The stones are 0.02ct to 0.20ct in D-J colour.

The below results demonstrate the performance of the SYNTHdetect with the ASSURE 1.0 Smalls Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 1.9%
Diamond Accuracy Rate (optimal rate 100%): 98.1%
Speed (stones tested per hour): 583

The 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.

Instrument Capabilities

Automated feed: No
Automated results: No
Automated dispense: No
Detect or Refer (synthetic diamonds) Refer
Detect or Refer (diamond simulants) Refer
Multiple stones at once: Yes
Training required: Yes

SYNTHdetect captures images and based on visual analysis of the images the instrument automatically displays one of the following results that can be interpreted by the operator:

  1. Natural
  2. Refer

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

The instrument does require user interpretation although it contains the software to aid in this interpretation. 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.
