Tester per diamanti incolori Presidium Synthetic Diamond Screener SDS II

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

Functionality

Type IIa colourless synthetic diamonds can be obtained by chemical vapour deposition (CVD) or high pressure, high temperature (HPHT) synthesis, or they can be HPHT-treated CVD diamonds.

Type IIa diamonds transmit deeper UV light and thus their UV light absorption is low.

Application

This device, designed exclusively for use on colourless diamonds (D to J colours), features a safe, user-activated deep-wave UV light source that passes through the tested stone and directs it towards the photodetector on the base platform inside the product. Coloured light bars on the front of the cover provide an intuitive readout to indicate whether the UV light absorption capacity of the tested stone is low (indicative of a Type IIa diamond) or high (indicative of a natural diamond).
