The tester here uses thermal conductivity to test diamonds. It is fitted with a UV light that can be used during a test to give more accurate readings on moissanite. It can also be used to observe the fluorescence in diamonds for the purpose of color-grading.

• Moissanite registers as a diamond on diamond testers.
• Moissanite has the same thermal conductivity as diamonds.
• Measures electrical conductivity.
• Tests loose stones or stones mounted in jewelry.
• Fitted with a built-in metal alert.
• Helps eliminate false readings.
• Fitted with an illuminating band around the probe.
• Probe lights up in different colors to correspond with the test results.
• Fully automatic.
• Requires no calibration.
• Easy and simple to use.
• Powered by one standard 9V battery or optional AC power supply.
