PRESIDIUM Synthetic Diamond Screener II (SDS II)

Synthetic Diamond Screener II (SDS II)

The Synthetic Diamond Screener II is developed by Presidium to help screen out Type IIa colorless diamond, which is likely to be synthetic and created through chemical vapor deposition (CVD) or high pressure high temperature (HPHT) syntheses, from the natural Type Ia colorless diamond.

• Blue light to illuminate the testing pad
• A 5mm metal bar to conveniently raise the test probe for successive testing on loose stones
• Test button will blink in red to alert if the device is unable to detect any stones on the photo-detector
• Auto shutdown of interior LED light source for safe testing when lid of device is open or when Start Test button is not activated
• USB port for alternative power source and connectivity
