The user calibrate the tester then place the loose stone on the stone-tray. Touch the ‘START’ button on the screen to start testing then place the probe tip onto the stone within the table facet area of the gemstone perpendicularly and Optimum-I will start testing and interpret the results automatically.
Optimum-I makes a measurement and displays one of the following results:
The ‘Type IIa (IaB) refer to lab’ and ‘Need investigation’ results could contain potential synthetic diamonds and diamonds. These referrals should be test further for full verification.
