A diamond tester is a portable device used to determine whether a gemstone is a real diamond. It works by measuring:
- Thermal conductivity – Diamonds conduct heat better than most imitation stones.
- Electrical conductivity – Some testers distinguish between diamonds and moissanite (which conducts electricity).
Popular brands include Presidium, GemOro, and Culti Diamond Testers.
