If you, or I should say your intended, like moissanites than that is what you should get. But, I want to give you some extra information just in case you are an information nut like me.
Moissanites do not look like diamonds. Well they do, but they are easily distinguishable. Know one could mistake a moissanite and a diamond. Correct that moissanites are a created gemstone and not a simulant diamond like cz's, but cz's are in fact closer in look and performance to an actually diamond (at least the good ones.) Also, moissanites tend to have a warmer yellowish to greenish color hue. Most are around a j/k compared to the diamond color scale. Some are greenish though. Moissanites are double reflective, meaning that the pavillion facets reflect light back up to the table twice. Some like this, most do not.
The good quality simulant diamonds such as diamondique, or better yet, Van Graffs are very similar in look and light performance (brillance, fire, dispersion) to diamonds. Van Graffs are typically very white, around d-f on the diamond color scale, and internally flawless. Moissanites usually are very included.
Here is a qoute from a person who owns both moissanites and Van Graffs.
"Yes, I have seen Van-Graff and Moissanite side by side in a similar size and identical shape. There really is no comparison. To me, the VG is that much more beautiful and believable, and I am a person who actually likes moissanite. (Many here do not.) I don't mind the warm tint of moissanite and I enjoy the dispersion, but it can't be considered a good diamond simulant when stacked up against even ordinary CZ. Moissanite is moissanite. The Van-Graff is an incredibly beautiful diamond simulant, and it is also much more affordable.
The differences I saw in the moissanite and Van-Graff were:
1) Moissanite is much, much darker. It does not have the brilliance of the VG. This makes the VG look much larger even in the same size.
2) Moissanite is much more yellow. I have seen different qualities of moissanite: some are hideously green, the one I was looking at was an attractive warm tint. The difference was marked.
3) Moissanite's larger dispersion was mostly invisible. Because the VG was so much brighter, it appeared to be giving off more fire even if I know that moissanite has a higher dispersion.
4) Moissanite is cut funny. I don't know a more technical way to put this. I believe I had read that moissanite is cut in a way to show the beauty of moissanite. The round brilliant cut really didn't look like the VG cut in the same size.
5) Moissanite is fuzzy. The double refraction of the facets makes the stone look fuzzy or blurred when viewed through a crown angle. It does not have the crisp, diamond-like look of the VG.
I enjoy moissanite. I wouldn't turn one down. However, I feel that the VG is a much more believable, beautiful, and affordable diamond sim. I prefer the VG. "
Now as I said, if your intended likes moissanite than that is wonderful, I would just like to see you and her make a well informed decision. Also, make sure you do not buy a moissanite without seeing it first hand as there are many moissanites with poor cuts, color, clarity.
