AMS2 is a desktop fully automated diamond verification instrument. AMS2 is designed to screen large quantities of loose stones at high speed. AMS2 automatically separates diamonds, synthetic diamonds and diamond simulants. The operator loads up to 500 carats of loose polished stones into a the AMS2 within a specific size range. The instrument then automatically processes the stones and physically dispenses them into their respective categories.
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
Key performance metrics measured for the AMS2 with the ASSURE 2.0 Primary Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 0.7%
Diamond Accuracy Rate (optimal rate 100%): 99.3%
The 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.
Key performance metrics measured for the AMS2 with the ASSURE 2.0 Smalls Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 0.6%
Diamond Accuracy Rate (optimal rate 100%): 98.6%
The Smalls Sample is tested three times and consists of 350 loose diamonds, 100 loose synthetic diamonds and 50 loose diamond simulants. The stones are 0.005 ct to 0.02 ct in D-J colour.
The AMS2 is a fully automated instrument and has a measured operating speed of 2,300 stones per hour.
Automated Feed: Yes
Automated Results: Yes

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 requires periodic calibration.
