DIATRUE CS

DIATRUE CS is a desktop diamond verification instrument for loose and mounted diamonds. DIATRUE CS is designed to separate natural diamonds from synthetic diamonds. DIATRUE CS is manually operated and gives a semi-automatic test results.

The performance metrics shown below are based on testing done in 2020 using the ASSURE 1.0 test standard and sample sets. The DIATRUE CS has not been tested under ASSURE 2.0.

Instrument Performance

The below results demonstrate the performance of the DIATRUE CS with the ASSURE 1.0 Core Sample when tested by a Novice Operator:

Diamond False Positive Rate (optimal rate 0%): 4%
Diamond Referral Rate (optimal rate 0%): 0%
Diamond Accuracy Rate (optimal rate 100%): 93.7%
Speed (stones tested per hour): 201

The ASSURE 1.0 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.

Instrument Capabilities

Automated Feed: No
Automated Results: Semi-automatic
Automated Dispense: No
Detect or Refer (Synthetic Diamonds): Detect
Detect or Refer (Diamond Simulants): Detect
Multiple Stones at Once: Yes
Training Required: No, review user manual

DIATRUE CS measures multiple stones and semi-automatically displays one of the following results:

Diamond
Synthetic diamond (separate HPHT and CVD)
Refer

The ‘Refer’ result could indicate a potential synthetic diamond or natural diamond. DIATRUE CS has a special ‘refer function’. If operator still has a doubt after utilizing the ‘refer function’ OGI recommends further testing by a gemmological laboratory.
