Metamorphic

This is Formula X Metamorphic:

It's a metallic gray microglitter, basically, to the point of reading as a dark silver - or I guess pewter, you might say. This is from the Liquid Crystals collection. Formula X apparently described it as "sheer" but it goes pretty opaque in two coats. (Temptalia has some comparison swatches.) (As with almost all of my Formula X polishes, I bought it marked down so it's almost certainly discontinued.)
