SYNTHdetect

SYNTHdetect

SYNTHdetect is a desktop diamond verification instrument for loose and mounted stones. It is designed to separate diamonds from synthetic diamonds and diamond simulants. SYNTHdetect is manually operated and requires an operator to interpret the test results.

Stone Testing Capability

Weight: 0.001 ct-100 ct
Colour: D-J (failsafe across all colours although natural fancy colours will give a higher referral rate)
Shape: All
Diamond Simulants: Yes
Mounted Stones: Yes

Instrument Performance

Key performance metrics measured for the SYNTHdetect with the ASSURE 2.0 Primary Loose Stone Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 1.8%
Diamond Accuracy Rate (optimal rate 100%): 98.2%

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 SYNTHdetect with the ASSURE 2.0 Smalls Loose Stone Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 2.1%
Diamond Accuracy Rate (optimal rate 100%): 97.9%

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 SYNTHdetect was 170 stones per hour.

Key performance metrics measured for the SYNTHdetect with the ASSURE 2.0 Primary Mounted Stone Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 0.4%
Diamond Accuracy Rate (optimal rate 100%): 99.6%

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 SYNTHdetect with the ASSURE 2.0 Smalls Mounted Stone Sample:

Diamond False Positive Rate (optimal rate 0%): 0%
Diamond Referral Rate (optimal rate 0%): 0%
Diamond Accuracy Rate (optimal rate 100%): 100%

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: No
Automated dispense: No
Detect or Refer (synthetic diamonds) Refer
Detect or Refer (diamond simulants) Refer
Multiple stones at once: Yes
Training required: Yes

SYNTHdetect captures images and based on visual analysis of the images the instrument automatically displays one of the following results that can be interpreted by the operator:

  1. Natural
  2. Refer

The ‘Refer’ result could contain potential synthetic diamonds, diamonds and diamond simulants. These referrals should be tested further for full verification.

The instrument does require user interpretation although it contains the software to aid in this interpretation. SYNTHdetect needs to be calibrated periodically to ensure continued high performance. The user will be notified by the software when the calibration needs to be carried out. A calibration sample is supplied with the instrument.
