Synthetic Diamond Screener II (SDS II)
Enhanced with additional features, the Synthetic Diamond Screener II is a portable desktop device developed by Presidium to help screen out Type IIa colorless diamonds (usually CVD/HPHT laboratory-grown diamonds) from the natural Type Ia colorless diamond.
Enhanced with additional features, the Synthetic Diamond Screener II (SDS II) now tests for diamond melees as small as 0.02 carats with instantaneous results, through the measurement of UV absorption and helps to 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.
Works on both mounted (with open-back setting) and loose diamonds.
When subjected to this deep UV irradiation, Type Ia and Type IIa diamonds each absorb different amount of UV light. Type IIa diamonds allow more deep 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 and the device uses this as core principle of function.
