ASDI-500

ASDI-500

ASDI-500 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-500 uses a robotic arm to automatically separate diamonds from synthetic diamonds and diamonds simulants and is capable of handling stones down to 0.5mm in diameter.

Instrument Performance

The below results demonstrate the performance of the ASDI-500 by SSEF and UNIMEC with the ASSURE 2.0 Primary Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 12.8%
Diamond Accuracy Rate (optimal rate 100%): 87.2%

The ASSURE 2.0 Primary Sample is tested three times and consists of 350 loose diamonds, 100 loose synthetic diamonds and 50 loose diamond simulants. The stones are 0.02ct to 0.20ct in D-J colour.

The below results demonstrate the performance of the ASDI-500 with the ASSURE 2.0 Smalls Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 15.0%
Diamond Accuracy Rate (optimal rate 100%): 85.0%

The ASSURE 2.0 Smalls Sample is tested three times and consists of 350 loose diamonds, 100 loose synthetic diamonds and 50 loose diamond simulants. The stones are 0.005ct to 0.02ct in D-J colour.

The below results demonstrate the performance of the ASDI-500 with the ASSURE 2.0 Ultra-Smalls Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 15.7%
Diamond Accuracy Rate (optimal rate 100%): 84.0%

The ASSURE 2.0 Ultra-Smalls Sample consists of 350 loose diamonds, 100 loose synthetic diamonds and 50 loose diamond simulants. The stones are less than 0.002ct 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): Detect
Multiple Stones at Once: Yes
Training Required: Yes

The user loads a parcel of loose polished stones into the ASDI-500. The parcel must have a size range tolerance of +/- 0.05mm. ASDI-500 dispenses the stones into four categories:

  1. Diamond
  2. Refer
  3. Diamond simulant
  4. Not Analysed

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

Prior to starting an inspection, the ASDI-500 runs an automated internal calibration on a reference diamond included in the device. The calibration takes less than one minute. Following inspection, the ASDI-500 can export an inspection result file.
