How to Spot Moissanite SiC using only magnification for definitive results! Double Refraction!

Video demonstrates Double Refraction of Moissanite. Viewers should watch video using 4K resolution feature to better understand the presentation. This demonstration should take a few minutes to master the technique. Once viewer understands what it is that he/she is looking at you will understand what to look for to quickly segregate Doubly Refractive stones from Single Refractive stones.
After viewer has mastered this technique with a 10x magnification loupe he/she doesn't need to purchase an expensive moissanite electric conductivity probe tester! The testers cannot detect coated moissanites as the conductivity is most often undetectable without using an ultra-violet light source to further excite the atoms.
