Presidium Synthetic Diamond Screener II

THE SYNTHETIC DIAMOND SCREENER II IS DEVELOPED AS A PORTABLE PRESIDIUM DIAMOND VERIFICATION INSTRUMENT® TO HELP SCREEN OUT TYPE IIA COLORLESS DIAMOND, WHICH IS LIKELY TO BE LABORATORY-GROWN AND CREATED THROUGH CHEMICAL VAPOR DEPOSITION (CVD) OR HIGH PRESSURE HIGH TEMPERATURE (HPHT) SYNTHESES, FROM THE NATURAL TYPE IA COLORLESS DIAMOND.WHEN SUBJECTED TO THIS DEEP UV IRRADIATION, TYPE IA AND TYPE IIA DIAMONDS EACH ABSORB DIFFERENT AMOUNT OF UV LIGHT. TYPE IIA DIAMONDS ALLOW DEEPER UV LIGHT TO PASS THROUGH AND THUS ITS UV LIGHT ABSORPTION ABILITY IS LOW. THIS DIFFERENCE IN THE LIGHT ABSORPTION IS SIGNIFICANT ENOUGH TO AID IN DIFFERENTIATING BETWEEN COLORLESS TYPE IA AND TYPE IIA DIAMONDS.
