This compact tool brings professional thermal conductivity testing into a design that anyone can use with ease. Power it on, allow a brief moment for stabilization, then place the probe directly on the stone’s surface. Clear LED indicators, a responsive beep, and a readable display work together to confirm whether the gem is authentic.
The device is built from a mix of lightweight metal and durable plastic, giving it a sturdy feel without adding bulk. Its shape makes it easy to handle, especially during quick evaluations or on-the-go inspections.
The thermal probe reacts consistently to genuine diamonds and does not trigger on common substitutes like cubic zirconia, offering dependable differentiation for collectors and enthusiasts.
As soon as the correct reading is detected, the indicator lights make your result obvious at a glance, even in low-light conditions such as workshops or trade settings.
A helpful alert notifies you if the probe touches metal instead of the stone, reducing the chance of false outcomes during fast-paced evaluations.
Its compact dimensions make it ideal for travel, retail counters, gemstone fairs, or at-home verification sessions.
The straightforward interface keeps the learning curve extremely low, so both beginners and experienced jewelers can work with equal confidence.
A simple pouch makes it easy to store, helping protect the probe and keeping the tester ready for your next appraisal.
The tester runs on a commonly available 9V battery, providing convenient, cable-free operation during field inspections or routine checks.
Elevate your gemstone evaluations with a dependable tool that brings accuracy and peace of mind to every test.
