The user manually places the loose or mounted stones inside the test chamber of the instrument. To start the testing, the user closes the test chamber and press the scan button.

 

ALROSA DIAMOND INSPECTOR automatically makes a measurement and displays one of the following results:

 

  1. ‘Natural
  2. ‘TYPE IIa (IaB) Refer to Lab.’
  3. ‘Treated’
  4. ‘Need investigation’
  5. ‘Simulant’
  6. ‘Check stone’

The ‘TYPE IIa (IaB), Refer to lab’ and ‘Need investigation’ results could contain potential synthetic diamonds and diamonds. These referrals shall be tested further for full verification. ALROSA recommends further testing of referred stones by a gemmological laboratory.
