Oh wow. Avon tends to be tame with polish but they sometimes release some great ones. This is one of them. It's what I wanted OPI Designer Series Mystery to be. This is a lush dark purple with flecks of gold shimmer. I see other colors of shimmer in there as well but the gold stands out. It's not too dark to be mistaken for black and the shimmer isn't subtle. Not bad for about $3.
Wacky Laki did a great manicure with it that I love. I may have to steal the idea.
