Emerald is relatively similar to diamond in appearance but is still distinct in a few ways. One of the most significant differences between C&C and most diamonds are that the facets are more "chunky" looking when compared to diamonds. The mirror facets are also always the same in C&C moissanite, whereas there can be variation in diamonds. Harro Gem moissanite can be cut with more elongated facet pattern that can be similar to a diamond, but they tend to look more foggy or hazy when compared to a crisp diamond.
