Presidium Synthetic Diamond Screener II Jewelry Tester Testing Tool

Description

The Presidium Synthetic Diamond Screener II (SDS II) is a portable desktop device that helps screen for colorless Type IIa diamonds, which are potentially lab-grown (CVD or HPHT), from natural Type Ia diamonds by measuring their UV light transmittance ability.

Key Features & Specifications

Technology: Utilizes deep-wave UV light source to measure a diamond’s UV light absorption ability.

Gemstone Suitability: Designed for use on colorless diamonds only, ranging from D to J color, and approximately 0.02 to 10 carats in size. Not suitable for colored diamonds, moissanite, or cubic zirconia.

Testing Capability: Can test both loose stones and those already mounted in jewelry (provided they have an open-back setting).

Speed: Provides instantaneous results, typically within 2 seconds.

Indicator Lights: Features two color-coded light bars: a blue light for high UV absorption (indicating a natural Type Ia diamond) and a red light for low UV absorption (indicating a Type IIa diamond, which may be synthetic and requires further testing).

Portability & Power: The device is lightweight and portable, powered by either 4 AAA batteries or via a USB connection.

Safety: Includes an auto-shutdown feature for the interior LED light source when the lid is open or not in use, ensuring safe operation.
