GIA iD100 by GIA (Gemological Institute of America)

Instrument Description

GIA iD100 is a portable desktop diamond verification instrument for mounted and loose stones. GIA iD100 is designed to separate diamonds from synthetic diamonds and diamond simulants. GIA iD100 is manually operated but gives an automatic test result. GIA iD100 is suitable for an environment where you need to test both mounted and loose diamonds e.g. dealers, diamond and jewellery manufacturers, retailers, buyers and gemmological laboratories. ASSURE ID: 75549.

How Does it Operate?

The instrument tests individual stones and automatically displays a test result. The user manually places the measurement probe onto the stone and the instrument automatically makes a measurement and displays a result.

 

The GIA iD100 displays one of the following results:

 

  1. ‘Pass’
  2. ‘Refer’

 

The ‘Refer’ results could contain potential synthetic diamonds, diamond simulants or diamonds. These referrals shall be tested further for full verification. GIA recommends further testing by a gemmological laboratory.

 

Room light calibration is needed upon starting the GIA iD100. At the touch of a button, the system evaluates the existing light in the environment and uses the information to improve the device sensitivity, taking approximately 5 seconds. Calibration is needed once per day or whenever the environmental lighting conditions are changed.

 

ASSURE Test

GIA iD100 was tested in accordance with the Diamond Verification Instrument Standard with the test protocol for instruments that separate diamonds from synthetic diamonds (Operation Category 2).

 

The tests took place at the independent laboratory UL in Canton, Massachusetts, United States. The tests were performed by a novice operator. GIA iD100 was tested with the ASSURE Core Sample and the ASSURE Smalls Sample.

 

The UL test report including more detailed test results can be found here.

 


ASSURE Core Sample

The ASSURE Core Sample consists of 1,000 loose diamonds, 200 loose synthetic diamonds and 200 loose diamond simulants. The stones are 0.02 ct to 0.20 ct in D-J colour. The below results are from the test with the ASSURE Core Sample.

 

Diamond False Positive Rate Ratio of synthetic diamonds and diamond simulants incorrectly classified as 'diamond' to the total number of synthetic diamonds and diamond simulants 0%
Diamond Referral Rate Ratio of diamonds being referred for further testing to the total number of diamonds 3.3%
Diamond Accuracy Ratio of diamonds correctly classified as diamonds to the total number of diamonds 96.7%
Speed Stones tested per hour 183
ASSURE Smalls Sample

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. The below results are from the test with the ASSURE Smalls Sample.

 

Diamond False Positive Rate Ratio of synthetic diamonds and diamond simulants incorrectly classified as 'diamond' to the total number of synthetic diamonds and diamond simulants 0%
Diamond Referral Rate Ratio of diamonds being referred for further testing to the total number of diamonds 4.2%
Diamond Accuracy Ratio of diamonds correctly classified as diamonds to the total number of diamonds 95.8%
Speed Stones tested per hour 183
