As one of the best and most popular modern gemstones, moissanite is used in jewelry design and made into moissanite rings, moissanite chains and bracelets, etc. Moissanite has many characteristics that can be flush with diamonds, so it has always been called the best diamond alternative. Does moissanite pass diamond tester when hardness and refraction are both high?

What is moissantie?
Moissanite was first discovered by French chemist Henri Moissan in a meteorite crater in 1893, hence the name “Moissanite”. Moissanite is a carbide mineral with a crystal structure similar to diamond. Moissanite has a Mohs hardness of 9.25, second only to diamond (Mohs hardness is 10), and is one of the harder gemstones in nature. Moissanite has a refractive index of 2.65–2.69, while diamond has a refractive index of 2.42. Moissanite double refraction and a higher refractive index allow moissanite to reflect light better, making it look more dazzling. Although natural moissanite is relatively rare, its price is still much lower than diamond. This is one of the reasons why many people choose moissanite. Its affordability makes it possible for many people to buy gemstones.
How does a diamond tester work?
How a thermal conductivity tester works: Diamonds have extremely high thermal conductivity. When the tester’s probe touches the gemstone, the instrument determines whether the gemstone is a diamond by detecting the speed of heat conduction. If the heat quickly passes through the test needle and transfers to the gemstone, the device will display the result of a diamond because the thermal conductivity of diamond is higher than that of most other gemstones.
How a conductivity tester works: A conductivity diamond tester detects whether it is a diamond by testing the ability of an electric current to flow through the gemstone. Since diamonds have a lower electrical conductivity, the resistance to electric current passing through diamonds is greater, while most imitation diamonds or non-diamond gemstones have a higher electrical conductivity, so they will have less resistance to the current.
How to use a diamond tester?
- Preparation before diamond testing: Make sure the tester is in working order. Some diamond testers need to be plugged in, while others are battery powered. Check that the battery is charged, make sure the device is clean, and that the test head (needle) is at the appropriate temperature.
- Power on test: Turn on the diamond tester and wait for the device’s self-test process to complete. Some devices may emit a prompt sound or a flashing indicator light to indicate that it is ready for testing.
- Contact the gemstone: Gently touch the test head to the top of the gemstone (usually the flat part of the gemstone). Make sure that the test head is in full contact with the surface of the gemstone to avoid testing errors.
- Read the results: Within a few seconds, the tester will display the results. Most thermal conductivity testers use indicators or sounds to inform the results. If it is a diamond, the instrument may make a “beeping” sound or a green indicator light; if it is a simulated diamond or other gemstone, the instrument will emit a different prompt sound or display a different color.
- Verification: If the instrument shows a diamond, you can confirm its authenticity. If it shows a non-diamond, you can recheck the position of the gemstone or perform more tests and use other types of testing instruments to confirm.
Does moissanite pass diamond tester?
Moissanite has very similar physical properties to diamond. Moissanite’s thermal conductivity is also very high, only slightly lower than diamond. The tester usually determines whether it is a diamond by testing the thermal conductivity of the gemstone, so in many cases moissanite can and will pass the diamond tester. If you are not sure whether the test result is accurate, after using the traditional and professional thermal conductivity diamond tester to test it as a diamond, you can also use other professional gemological tests, or perform spectrophotometry tests to further confirm.
Does Moissanite Pass Diamond Tester - Does lab diamond or fake diamond pass diamond test?
The development of technology has made the properties of almost all lab grown diamonds indistinguishable from those of natural diamonds, including thermal conductivity. Therefore, diamond testers based on the principle of thermal conductivity cannot distinguish between artificial diamonds and natural diamonds, and they will pass the test just like moissanite. Moissanite vs lab diamond are very similar in unique peculiarity. Moissanite and lab grown diamonds are among the few fake diamonds that pass diamond testers. Other fake diamonds, such as cubic zirconia, have thermal conductivity far worse than diamonds, and therefore cannot pass diamond tests.
Does Moissanite Pass Diamond Tester - What stones will pass a diamond tester?
Moissanite can pass a diamond tester due to its similar thermal conductivity to diamonds, making it possible for diamond tester passing jewelry to include both real diamonds and moissanite. However, not all stones will pass; cheap jewelry that pass diamond tester often includes synthetic stones or low-quality materials like cubic zirconia that may show similar results under specific conditions, but they lack the other properties of real diamonds.
Conclusion
We told does moissanite pass diamond tester this article. Moissanite is known as the best and most realistic diamond substitute because its properties are similar to diamonds, and some are even better. Even a diamond tester cannot tell the difference between diamonds and moissanite. The dazzling moissanite ring is also a popular choice for wedding rings. If you want to buy a moissanite ring, Amanda’s moissanite ring collections provides you with many choices.
FAQs About Does Moissanite Pass Diamond Tester
How to read a diamond tester? Do lab grown diamonds test positive on a diamond tester?
Place the probe on the stone; the tester will show a color or sound. The diamond tester color meaning indicates whether the stone is a diamond or not, with green/red often signaling a real diamond. Yes, lab-grown diamonds test positive, as they have the same properties as natural diamonds. Both will show similar results on a diamond tester.
How does moissanite pass diamond tester? Why does moissanite pass diamond tester?
Moissanite passes a diamond tester because it has a similar thermal conductivity to diamonds. The tester detects heat transfer, and since moissanite conducts heat almost as well as a diamond, it gives a positive reading.
Why does moissanite test as a diamond? How to tell a diamond from a moissanite?
Moissanite tests as a diamond due to its high thermal conductivity. To tell them apart, look for differences in fire and brilliance: moissanite has more sparkle and fire, while diamonds have a more subdued brilliance. Additionally, moissanite displays a “double refraction” under magnification.
Does vvs moissanite and cubic zirconia pass a diamond tester?
VVS moissanite will pass a diamond tester, just like other moissanite stones, due to its similar thermal properties to diamonds. Cubic zirconia typically will not pass because its thermal conductivity is much lower than that of diamonds.
Can I use diamond tester online? What’s the diamond tester price?
You can’t use a diamond tester online; it’s a physical tool. The price of a diamond tester varies, typically ranging from $20 to $200 depending on quality and brand.
