GV5000

GV5000

GV5000 is a desktop diamond verification instrument for loose and mounted stones designed to separate diamonds, synthetic diamonds and diamond simulants. GV5000 is manually operated and requires an operator to interpret the test results.

Stone Testing Capability

Weight: 0.002 ct-20 ct
Size: 0.7 mm-20 mm
Colour: D-N
Shape: All
Diamond Simulants: Yes
Mounted Stones: Yes (not yet ASSURE Tested)

Instrument Performance

The below results demonstrate the performance of the GV5000 with the ASSURE Core Sample:

Diamond False Positive Rate (optimal rate 0%): 1%
Diamond Referral Rate (optimal rate 0%): N/A
Diamond Accuracy Rate (optimal rate 100%): 98.5%
Speed (stones tested per hour): 296

The ASSURE 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 GV5000 with the ASSURE Smalls Sample:

Diamond False Positive Rate (optimal rate 0%): 0.3%
Diamond Referral Rate (optimal rate 0%): N/A
Diamond Accuracy Rate (optimal rate 100%): 97.5%
Speed (stones tested per hour): 296

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.

Instrument Capabilities

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

GV5000 captures multiple images and based on visual analysis of the images, and support from a decision tool, the operator concludes the nature of the stones.

The following results can be concluded by the operator based on the data generated by the GV5000:

  1. Diamond
  2. Synthetic diamond
  3. Diamond simulant
  4. Refer

The ‘Refer’ result could contain potential synthetic diamonds and diamonds. These referrals should be tested further for full verification. GV5000 need to be recalibrated before usage or after it has been moved.
