DiaMetric – Diamond Measurement & Sorting Machine
DiaMetric is an advanced digital diamond measurement and sorting machine, engineered for speed, accuracy and complete traceability. It measures every diamond’s length, width and diameter with an accuracy of ±10 microns, in less than 1 second per diamond, and instantly shows the operator which box the stone belongs to.
Built for 17 shapes, from Round, Oval, Pear and Marquise to Princess, Emerald, Baguette and Trillion, including Polki and free-form stones, DiaMetric applies the right measurement method to every shape. Beyond size, it can also measure side lengths, corner angles, tip angle, symmetry, L/W ratio and, for Polki, the stone’s area (spread), shown live on the screen on the diamond’s image.
Every diamond is recorded automatically. Live box-wise counts, Excel records and one-click branded PDF and Excel reports remove paperwork completely and give you a reliable record for buyers, audits and your own team.
With easy calibration using your own reference diamond, smart Undo / Redo, and data that stays safe even through a power cut, DiaMetric is the ideal smart investment for diamond manufacturers, sorting units and traders.
