moissanite

An alternative to diamonds, moissanite is a great choice (unlike Cubic Zirconia (CZ)) if you want an iced out piece for thousands less. Real diamonds usually don't reflect a lot of colors, usually white & blue, while on the other hand moissanite stones reflect a much larger spectrum. The majority of moissanite stones will pass a basic diamond tester, but will show up as "Moissanite" on farther advanced lab assays.

"Wow, his chain is dancing like crazy, must be moissanites as my real diamond chain doesn't do that."
