Zoya Gem vs Zoya Valerie

Gem and Valerie are both pretty popular plum shades for Zoya.  I can totally see why, because to me I can barely tell the difference.  Valerie definitely has more and larger glitter than Gem.  Valerie's formula was also a little thicker than Gem.  If you look closely, you can see the surface reflection in Valerie is a bit rougher.  Gem is much smoother with a finer particulate of sparkle.  Gem also applied a bit smoother with easier control.

I would say that you can own one or the other, but you probably don't need to own both.  If you like more sparkle, go with Valerie.  If you want something a little more muted, pick up Gem.  Here is 2 coats of Gem with 1 coat of nubar Diamont.
