GIA iD100
GIA iD100 is a portable desktop diamond verification instrument for mounted and loose stones designed to separate diamonds from synthetic diamonds and diamond simulants. GIA iD100 is manually operated but gives an automatic test result.

Instrument Performance
Key performance metrics measured for the iD100 with the ASSURE 2.0 Primary Loose Stone Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 10.4%
Diamond Accuracy Rate (optimal rate 100%): 89.6%
The Primary Loose Stone Sample was tested three times and consists of 350 loose diamonds, 100 loose synthetic diamonds and 50 loose diamond simulants. The stones are 0.03 ct to 0.20 ct in D-J colour.
Key performance metrics measured for the iD100 with the ASSURE 2.0 Smalls Loose Stone Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 13.6%
Diamond Accuracy Rate (optimal rate 100%): 86.4%
The Smalls Loose Stone Sample was 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 measured test speed for the iD100 was 208 stones per hour.
Key performance metrics measured for the iD100 with the ASSURE 2.0 Primary Mounted Stone Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 7.4%
Diamond Accuracy Rate (optimal rate 100%): 92.6%
The Primary Mounted Stone Sample consists of jewelry pieces with open-back settings containing a total of 303 stones. The stones are a mix of diamonds, laboratory grown diamonds and diamond simulants in the D-J colour range and have a minimum girdle diameter of 2.0 mm.
Key performance metrics measured for the iD100 with the ASSURE 2.0 Smalls Mounted Stone Sample:
Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 4.3%
Diamond Accuracy Rate (optimal rate 100%): 95.7%
The Smalls Mounted Stone Sample consists of jewelry pieces with closed-back settings containing a total of 54 stones. The stones are a mix of diamonds, laboratory grown diamonds and diamond simulants in the D-J colour range and have a girdle diameter between 1.0 mm and 2.0 mm.
Instrument Capabilities
Automated Feed: No
Automated Results: Yes
Automated Dispense: No
Detect or Refer (Synthetic Diamonds): Refer
Detect or Refer (Diamond Simulants): Refer
Multiple Stones at Once: No
Training Required: Yes
The instrument tests individual stones and automatically displays one of the following results:
- Pass
- Refer
The ‘Refer’ results could contain potential synthetic diamonds, diamond simulants or diamonds. These referrals should be tested further for full verification.
Room light calibration is automatically initiated when turning on the iD100 and is required to be done once per day or whenever the environmental lighting conditions are changed.
