Moissanite is a 9.5/10 on the hardness scale, with diamond being a 10. Outside of industrial applications this is a totally insignificant difference. This reads like the other criticisms of moissanite I've read where people claim that it is "too shiny" making it look too much like a diamond you couldn't possibly afford and therefore giving away it's identity.

I'm not saying that moissanite's slightly lower hardness will cause problems in use as jewelry. I'm saying that, contra the parent comment's implication, it's very easy to tell the difference.

But you can only scratch it with something as hard as diamonds.Who is really considering that when buying jewelry? Resistent to blemish from everything but diamond...oh nooo...
It is extremely easy to distinguish a moissanite from a diamond using a reliable, low-tech test: the moissanite can't scratch a diamond, but a diamond will scratch the moissanite.
The problem, if you're a jeweler talking to a customer, is that this will damage the moissanite.
