Designed with an ergonomic grip and factory-tested components, the kit arrives ready to use (battery included) and targets fast, on-the-spot evaluation rather than laboratory-grade certification.\n\n\u003ch3\u003eHow does the Mollo Diamond Tester Pen determine whether a stone is a diamond?\u003c\/h3\u003e\n\u003cp\u003eThe tester uses a thermal conductivity probe to read heat transfer through the stone while the integrated torch highlights light colour effects.

It suits novices who need clear light-and-sound cues and experienced users who want a fast pre-screening device before sending pieces for formal lab analysis. The kit includes the diamond tester, a matching torch, and a battery, and comes from factory-direct stock with inspection and a replacement or refund option if defects are found. Follow the included warm-up and contact instructions for the most consistent results and remember this tool complements—rather than replaces—full gemological testing when certification is required.\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the Mollo Diamond Tester need calibration?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Basic calibration is built into the device; follow the startup check ensuring one light is lit.
