ASDI by SATTGEMS
Instrument Description
ASDI is a stationary fully automated diamond verification instrument. ASDI is designed to screen large quantities of colourless and near colourless loose stones at a high speed. ASDI automatically separate diamonds from synthetic diamonds and diamonds simulants. ASDI is suitable for large scale diamond wholesalers, diamond cutting and polishing sites, jewellery manufacturers, and gemmological laboratories. ASSURE ID: 43461.

How Does it Operate?
The user loads a parcel of loose polished stones into the ASDI. The instrument then automatically processes the stones and dispenses them into respective category.
ASDI dispenses the stones into three categories:
- Diamond
- Refer
- Diamond simulant
The refers could contain potential synthetic diamonds and diamonds. The referrals shall be tested further for full verification. SATTGEMS recommends further testing by a gemmological laboratory.
Additionally, ASDI can provide batch reports for up to 15 size measurements plus proportions for each diamond. ASDI is delivered with a series of master stones which can be tested anytime to ensure the correct calibration of the instrument.
ASSURE Test
ASDI was tested in accordance with the Diamond Verification Instrument Standard with the test protocol for instruments that separate diamonds from synthetic diamonds and diamond simulants (Operation Category 2). The tests took place at SSEF’s laboratory by a technician from the independent laboratory UL. The tests were performed by a novice operator. ASDI was tested with the ASSURE Core Sample and the ASSURE Smalls Sample.
The 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 | 6.4% |
| Diamond Accuracy | Ratio of diamonds correctly classified as diamond to the total number of diamonds | 93.6% |
| Speed | Stones tested per hour | 6,511 |
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 | 6.8% |
| Diamond Accuracy | Ratio of diamonds correctly classified as diamond to the total number of diamonds | 93.2% |
| Speed | Stones tested per hour | 6,511 |
