The easiest way to test a white round brilliant cut moissanite is to put it upside down over black text, you should not be able to see the text at all. See videos on youtube to see what you should see. 

Cut: Round Brilliant, Hearts & Arrows
Clarity: VVS1-Flawless

Hearts and arrows means that a round brilliant cut stone will show a hearts and arrows pattern under a hearts and arrows scope,
as shown in one of the pictures. It means that the stone is perfectly cut and whenever I get moissanite cut I ask for this cut, rather than just round brilliant.

About Moissanite

Moissanite was first synthesized in a lab before the natural mineral was found 2 years later by Henri Moissan in a meteor crator. Later Charles and Covard patented the mineral to be used to create gemstones. This patent has run out this year (2018) so now anybody can legally produce moissanite gemstones.  


Moissanite is visually close to a diamond, but has more fire than a diamond. CZ is a closer match to a diamond visually, but Moissanite is harder than cz and can pass as diamond with older electronic diamond testers, this will only work with moissanites (and diamonds) bigger than 2mm as smaller than 2mm is too small for most diamond testers. Moissanite can also pass the text test: That is if you put a diamond on a piece of text (black on white paper) you cannot see any black, moissanite passes this test also, cz doesn't. Moissanite can also scratch Sapphire and scratch cz as it is harder.
