Weight: 0.0033 ct-0.20 ct for round brilliants
Size: 0.90 mm-3.80 mm for round brilliants and 1.00 mm-4.00 mm for fancy cuts
Colour: D-J (failsafe across all colours although natural fancy colours will give a higher referral rate)
Shape: All
Diamond Simulants: Yes
Mounted Stones: No
The below results demonstrate the performance of the AMS2 with the ASSURE Core Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 0.7%
Diamond Accuracy Rate (optimal rate 100%): 99.1%
Speed (stones tested per hour): 2,677
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 AMS2 with the ASSURE Smalls Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 0.7%
Diamond Accuracy Rate (optimal rate 100%): 98.9%
Speed (stones tested per hour): 2,677
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.
Automated Feed: Yes
Automated Results: Yes
Automated Dispense: Yes
Detect or Refer (Synthetic Diamonds): Detect
Detect or Refer (Diamond Simulants): Detect
Multiple Stones at Once: Yes
Training Required: No
The user loads up to 500 carats of loose polished stones into the AMS2 in a specific size range. The instrument then automatically processes the stones and dispenses them into their respective category.
AMS2 dispenses the stones into four categories:
‘Refer’ could indicate potential synthetic diamonds and diamonds. The referrals should be tested further for full verification.
AMS2 needs to be calibrated periodically.
