Portable lamp designed for professional gem identification using UV fluorescence.
It uses a high spectral purity "cold light" LED source (long and short wavelengths) that produces a beam free of scattered visible light, increasing observation accuracy compared to traditional fluorescent lamps.

The Arcus Lab DK9800 Diamond Tester is a professional instrument specifically designed to quickly and accurately distinguish CVD-grown diamonds from HPHT-grown diamonds.
Important Notice
⚠ The DK9800 Arcus is NOT a universal diamond tester.
It should only be used after confirming that the stone is a laboratory-grown diamond using an appropriate screening instrument such as:

DK10300 APEX

Once a laboratory-grown diamond has been identified, the DK9800 determines whether it was produced using the CVD or HPHT growth method.

A complete solution for modern diamond testing
The combination of APEX + ARCUS LAB provides two complementary instruments:
1. APEX DK10300→ Identifies the type of stone and recognizes natural diamonds, synthetic diamonds, moissanite and simulants.
2. ARCUS LAB DK9800→ Provides further analysis of synthetic diamonds by distinguishing between CVD and HPHT growth methods.
A professional solution designed for those who want to face the challenges of the synthetic diamond market with greater confidence and provide customers with an accurate and reliable testing service.
