Hand-held, rechargeable multi-tester with 2 in 1 thermal and optical LED probe tip, for identifying Earth-mined diamond, Type IIa HPHT diamonds, Type IIa CVD diamond, Simulant and Moissanite (including F1). All-in-one testing probe having both thermal conductivity sensor and optical sensor. Testing probe uses copper tube with built-in optical fiber for the tip of the probe and bundled optical fibers forming an optical ring to illuminate a target stone with light source using internal UV LEDs. Short and long wave UV light can be used singularly or together. Sensors measure thermal conductivity and optical absorptivity by converting an amount of temperature change and incident light into an output and sending signals to microcontroller unit to give results using color LCD touch screen to display and with speaking results in multiple languages. In addition to thermal and short and long wave optical, testing for metal may be added to handheld tester.
