Diamond tester for colorless diamonds Presidium Synthetic Diamond Screener SDS II

Product information "Diamond tester for colorless diamonds Presidium Synthetic Diamond Screener SDS II"

The Synthetic Diamond Screener II (SDS II) is a lightweight, portable and robust diamond tester. It has been designed to distinguish colorless Type IIa diamonds, which may be synthetic, from natural colorless Type Ia diamonds. The device is powered by 4 AAA batteries or via the USB port.

Functionality

Type IIa colorless synthetic diamonds can be grown either using chemical vapor deposition (CVD) synthesis or High Pressure High Temperature (HPHT) synthesis, or can be HPHT-treated CVD diamond.

Type IIa diamonds transmit more deep UV light and therefore their UV light absorption is low.

Application

This device, meant only for use on colorless diamonds (Color D to J), features a safe, user-activated, deep-wave UV light source that passes through the tested stone towards the photo-detector on the base platform inside the product. Bars of colored lights on the front of the lid will provide an easy reading to indicate if the UV light absorption ability of the tested stone is low (i.e. indicative of a Type IIa diamond) or high (indicative of a natural diamond).
