Diamonds sparkle a lot more brilliantly due to their high refractive index.

(Moissanite is even better, so it should be preferred over diamonds unless I’m overlooking some other difference in their attributes?)

But plain glass gems look comparatively bland when used as jewelry.

Moissanite scratchers much easier.

I need a geologist to explain this one. Moissanite has a Mohs hardness of 9.5. I guess it is easier to scratch than a diamond, but the scratability should be indistinguishable between the two for all practical purposes.

Oh duh. I was so focused on optical qualities I didn’t even think about material ones.

Everything scratches easier than diamond. Moissanite is still very hard to scratch.
