Above & Below: Plum Aluminum is more of a lavender shade than plum, and it has a somewhat metallic finish. I used 2 coats on this and other than it needing a little thinner, as most of these do at this point, it covers nicely. I've used a matte top coat over this in the past, and it resembles the finish of the OPI Suede polishes.
Below: Purple Comet is a very grey-leaning lavender shade with tiny silver glitter pieces. It's shown with a flash in the first photo, and with no flash in the second shot.
Below: Matte Sapphire is interesting for a matte shade because it has silver glitter in it. Most of my matte shades from the present era don't have this added feature. Again, this one is getting quite thick so it needs some thinner (I always realize this too late!), but it covered nicely using 2 coats. While the finish is matte, it's not completely flat.
Below: Shooting Stars has much more pizazz than what I was able to capture in this indoor shot. I prefer to use this over a darker shade (Matte Sapphire in this case). This multi-colored massive glitter shade also has a very slight holo effect.
