The SmartPro Aura v2 is a diamond verification instrument for loose and mounted stones, designed to separate diamonds from laboratory grown diamonds. It is manually operated and has both an auto-detection mode (for LGDs) and manual screening mode based on visual comparison of UV image to reference images.

Diamond Referral Rate (optimal rate 0%): 6.4%
Diamond Accuracy Rate (optimal rate 100%): 93.6%
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.
Automated feed: No
Automated results: Yes – for LGDs. Manual interpretation for Natural Diamonds
Automated dispense: No
Detect or Refer (synthetic diamonds) Detect
Detect or Refer (diamond simulants) Refer
Multiple stones at once: Yes
Training required: No
The Aura v2 can screen multiple loose or mounted stones at a time arranged on trays, and can return the following results:
1) Natural Diamond
2) Synthetic Diamond (with red mark indicated on image)
3) Refer
Stones without a red mark need to be compared to the fluorescent reference images to confirm stone type. Stones without a clear match are considered ‘Refer’ and should be further tested for full verification.
The Aura v2 includes 360 degree detection for mounted stones by automatically rotating the Jewelry piece every 90 degrees.
