Are you looking to buy a diamond and moissanite tester? These handy tools help you tell the difference between real diamonds and moissanite, which looks very similar. This guide will help you pick the right one.
Key Features to Look For
1. Accuracy
The most important thing is accuracy. A good tester will reliably tell you if a stone is a diamond or moissanite. Look for testers that have a high success rate in tests.
2. Ease of Use
You want a tester that’s easy to use, even if you’re new to jewelry. Simple buttons and clear displays make testing quick and stress-free. Some testers have lights or sounds to tell you the results.

Check how the tester is powered. Some use batteries, while others are rechargeable. Good battery life means you can test more stones without interruption.
