J.Mini

J.Mini

J.Mini is a portable diamond verification instrument for loose and mounted stones, designed to separate synthetic diamonds from diamonds. J.Mini is manually operated and gives a semi-automatic test interpretation.

The performance metrics shown below are based on testing done in 2019 using the ASSURE 1.0 test standard and sample sets. J-Mini has not been tested under ASSURE 2.0.

Stone Testing Capability

Weight: 0.003 ct +
Size: 0.7 mm +
Colour: D-K
Shape: All
Diamond Simulants: No
Mounted Stones: Yes (not yet ASSURE Tested)

Instrument Performance

The below results demonstrate the performance of the J.Mini with the ASSURE 1.0 Core Sample:

Diamond False Positive Rate (optimal rate 0%): 15.6%
Diamond Referral Rate (optimal rate 0%): N/A
Diamond Accuracy Rate (optimal rate 100%): 93.9%
Speed (stones tested per hour): 935 

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 J.Mini with the ASSURE 1.0 Smalls Sample:

Diamond False Positive Rate (optimal rate 0%): 1.6%
Diamond Referral Rate (optimal rate 0%): N/A
Diamond Accuracy Rate (optimal rate 100%): 77.0%
Speed (stones tested per hour): 935

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: Semi-automatic
Automated Dispense: No
Detect or Refer (synthetic diamonds): Detect
Detect or Refer (diamond simulants): N/A
Multiple Stones at Once: Yes
Training Required: Yes

J.Mini automatically makes a measurement and displays one of the following results:

  1. Diamond
  2. Synthetic diamond
  3. Refer

In case of a query, J.Mini software has a troubleshoot option that connects the user with the DRC Techno Support team to get instant response.
