ASDI

ASDI

ASDI is a stationary fully automated diamond verification instrument, designed to screen large quantities of colourless and near colourless loose stones at a high speed. ASDI automatically separates diamonds from synthetic diamonds and diamonds simulants.

Stone Testing Capability

Weight: 0.002 ct-0.20 ct
Size: 0.85 mm-3.80 mm

Shape: Round
Diamond Simulants: Yes
Mounted Stones: No

Instrument Performance

The below results demonstrate the performance of the ASDI by SATTGEMS with the ASSURE Core Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 6.4%
Diamond Accuracy Rate (optimal rate 100%): 93.6%
Speed (stones tested per hour): 6,511

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 ASDI by SATTGEMS with the ASSURE Smalls Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 6.8%
Diamond Accuracy Rate (optimal rate 100%): 93.2%
Speed (stones tested per hour): 6,511

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: Yes
Automated Results: Yes
Automated Dispense: Yes
Detect or Refer (Synthetic Diamonds): Refer
Detect or Refer (Diamond Simulants): Refer
Multiple Stones at Once: Yes
Training Required: Yes (three-day course at SSEF)

The user loads a parcel of loose polished stones into the ASDI. ASDI dispenses the stones into three categories:

  1. Diamond
  2. Refer
  3. Diamond simulant

‘Refer’ could contain potential synthetic diamonds and diamonds. The referrals should be tested further for full verification.

ASDI can provide batch reports for up to 15 size measurements plus proportions for each diamond. ASDI is delivered with a series of master stones which can be tested anytime to ensure the correct calibration of the instrument.
