Moissanite Tester V3

This compact moissanite tester by GemTrue offers a cheap and highly efficient way to separate your real gemstones from manmade moissanite. With its 0.6mm electro probe, your moissanite tester is able to accurately distinguish moissanite from other stones. The tester pen itself features a user-friendly design and is easy to use by hobbyists and professionals alike. Simply touch your gem with the probe of your tester, and your gadget will instantly inform you on whether you’re dealing with moissanite. In case the stone you’re testing is moissanite, the large illuminated panel placed right above the top of the tester will light up. When it is any other stone, including diamond, your tester will give no response. This makes it easy to analyze whether a stone is a moissanite or something else.

Moissanite testers are commonly used in combination with a regular diamond tester. After using your diamond tester to separate your diamonds from your other rocks, you can use the moissanite tester to separate the manmade diamonds from the precious natural ones. Like this, you can be assured that all your diamonds are 100% natural and authentic. Those of you who wish to speed up the process and do not want to use two testers for each stone are advised to use a multi-tester such as the GemTrue Experior DK9000. These multi-testers are able to distinguish both diamonds and moissanite, thus combining the functions of a diamond tester and moissanite tester into one little device.

The moissanite tester features a sleek and lightweight design. It furthermore has a professional rubber coated body for anti-slip purposes to ensure comfortable handling. Your moissanite tester is fully automatic and requires no user calibration. Thanks to this, you can be guaranteed to undergo highly precise test results anytime you use this advance tester pen. The tester also comes with a metal alarm that informs you when you accidentally touched the stone holder or jewelry in order to eliminate false readings. This makes your moissanite tester perfect to be used at both loose rocks as well as gems mounted in jewelry.

With its built-in UV light, your moissanite tester allows you to check your diamonds for the presence of fluorescence. The tester is extremely fast. It treats you to instant test results and requires no waiting time in between the testing of different gemstones. With its powerful 9v battery, your gizmo is able to get you through the longest of days. This moissanite tester has been designed in such a way that it can be used comfortably by left- and right-handed people alike.

Please note that moissanite testers only use electroconductivity. Because of this, they are not able to point out natural diamonds. Instead, they will only tell you when a stone is a moissanite. When the tester comes in contact with a diamond, it will not give any reaction. In order to find natural diamonds, you either need a conventional diamond tester pen or a multi-tester that can differentiate between diamonds, moissanite, CZ, and other sorts of rocks.
