Diamond Tester 2/3 Pen

The Ruth's sister Diamond Tester 2/3 Pen is a professional tool designed for jewellers, gemmologists and watch specialists who need to verify diamond authenticity. It uses thermal conductivity principles to separate genuine diamonds from common simulants. The handheld pen format allows quick, on-the-spot assessment during valuation or retail transactions.

LED Indicator Readout

A built-in LED indicator provides an immediate visual result, lighting to confirm diamond or remaining inactive for non-diamond materials. The device operates as a standalone test pen without requiring an external display or computer connection. Buyers who need laboratory-grade spectroscopic analysis or automated data logging should consider a different instrument class.

Questions about this item

What does the 2/3 selector do when I am testing a stone?

The selector switches the tester between two sensitivity levels so it can distinguish diamonds from moissanite and other simulants with a single probe.

How does the LED indicator show the result?

The built‑in LEDs light up in a sequence that tells you instantly whether the stone registers as diamond, moissanite or another material.
