Moissanite is a popular diamond simulant that is sold by jewelers as an alternative to a pricey diamond ring. It was first mass produced by Charles and Colvard and the patent they held gave them exclusive rights to make them.
In this video, I had purchased a loose moissanite gemstone from Charles and Colvard for about $100. It was then mounted onto a temporary ring holder to facilitate the test with the diamond tester.
As you will see in the video, the diamond tester actually identifies moissanite as a diamond. And this is actually an erroneous result because of the limitations of the testing equipment.
This cheap diamond tester uses a heat probe to check for a gemstone's thermal conductivity. While the majority of simulants like CZ or white sapphire can be detected, it fails to correctly identify moissanite. This is because moissanite has a similar heat transfer property like a real diamond.
If you want to correctly identify a moissanite, you will either have to use a higher end diamond tester that has an in-built electrical conductivity test or manually use a 10X loupe to check for doubling effects in the facets.
Here's a quick tutorial on how to use a 10X loupe if you need it:

If you are thinking about buying a gemstone from a dubious source, you need to learn to protect yourself with knowledge and the best way not to get scammed into buying a fake diamond is to shop at a reliable place.

FAQ: Does moissanite look like a diamond?
Answer: No. Mossanite is cut differently from a diamond to give it more fire. It also looks more oily and cloudy compared to a diamond which generally looks crisp and clean.
FAQ: Moissanite vs diamond sparkle - which is better?
Answer: Better is subjective. Diamonds can be cut to a variety of cut standards which affects their light performance. In general, better cut diamonds cost more and display a good balance of fire and brilliance. Likewise, moissanite is also subjected to the same kind of cutting standards. There are well cut moissanites and there are poorly cut moissanites. If we were to compare the top tier of moissanite and diamond cut quality, I would say that diamond would come out tops.
