SDS II by Presidium has achieved 100% Laboratory Grown Diamond Referral Rate when ASSURE TESTED. 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. The SDS II uses advanced technology that measures a diamond’ s UV light transmittance ability. It is a portable desktop diamond verification instrument suitable for both loose and mounted stones, including melees as small as 0.02ct. Easy to use and battery-operated, its indicator light bars give a blue light to indicate that the stone is a natural diamond and a red light to indicate a Type IIa diamond. The device gives clear and accurate results within two seconds.


· 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.

· Advanced technology that measures a diamond’ s UV light transmittance ability

· 2 colour coded (blue/red) indicator light bars to give a low or high reading of UV light absorption with blue light indicating Natural Diamond and red light indicating Type IIa Diamond

· Instantaneous clear results within 2 seconds

· 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

· Exterior base foam padding to ensure non-slip sturdiness and prevent scratches to surfaces

· Low battery indicator

· Energy-saving auto power-off of device after 10 minutes without operation

Size: 130 L x 100 W x 65mm High - 110g (without batteries)

Requires: 4 x AAA batteries

About ASSURE Program:

The ASSURE Program, by the Diamond Producers Association (DPA) has developed a universal standard to test the performance of Diamond Verification Instruments in a consistent way, with the aim of protecting the integrity of the global jewelry supply chain. The instruments are rigorously tested in a transparent manner against a unique common sample and standard. Each instrument is tested on the ASSURE Core Sample, a highly contaminated sample made up of 1,000 natural diamonds and 200 synthetic diamonds including very challenging synthetic diamonds, some of which are
