The ALROSA Diamond Inspector automatically takes 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 should be test further for full verification.
