Using a process of thermal conductivity, this unit provides both a visual and audio indicator of authenticity. WebThe thermal conductivity of moissanite is comparable to that of diamond, but unlike diamond, moissanite is an electric conductor. This test is often used to tell the two apart. Cost Diamonds cost about ten times more …
Web10 dec. 2024 · The operating temperature is within the range of 10-35 degrees Celsius, and the humidity is below 80% When testing diamond, your right index finger must keep touching the metal panel on the back of the tester. Please turn off the power after the test to save power. Package Content 1 x Diamond Tester 1 x 60X Microscope 1 x 9V battery WebYes and No. Yes, on most testers because they do not test for both thermal and electrical conductivity. A Moissanite does a very good job at masking itself as a diamond, with extremely similar properties such as hardness, clarity (although people believe it has more brilliant lighting) and thermal footprint.
