With a analytic, scientific, and accuracy-focused approach, the Gem Tester dissects products by rigorously examining refractive index accuracy, thermal conductivity speed, and lens magnification. Every review is crafted to answer the questions real buyers are asking before they commit to a purchase.
Our review process starts with a systematic examination of refractive index accuracy, thermal conductivity speed, and lens magnification, followed by stress-testing each claim against real-world scenarios. The goal: distinguish diamond from moissanite and gemstones correctly. Only products that pass earn a recommendation.
