Red Diamond is the second to last polish I've picked up from Azature's sparkly polishes. The last one to grab is the Yellow Diamond, but I'm not too sure I'll be picking that one up. They've very recently released some more polishes - all creme's - one of which I do own (which will be up next).
I do absolutely adore Azature's Diamond polishes. They're so incredibly sparkly. Some have issues with pooling or being very thick (or some having horrific staining)...but I still love them. Anyway...
Red Diamond is a classic red polish with holographic shimmer. My camera refuses to pick this up correctly. It's a cross between a jelly and a creme. I used two coats for this polish and had no major issues with it (including staining - yay!)
