Sorry it took so long, but here are the swatches!
Moonsand, a pewter-silver foil. I love foils, and Diamond does some great ones. In the bottle I thought it had a slight bluish tinge, but it's really just a dark silver. The fact that it's more of a patina-ed silver color rather than a super shiny one makes it perfect for fall/winter. The formula was great, very easy to work with and they were dry to the touch quickly (as with most foils), but it took a few minutes for each layer to dry completely. I am wearing three coats in the picture.
Hypnotic. This is an intriguing green that leans toward teal, reminds me a dark green jade. It has a more yellow-toned emerald green shimmer, and maybe some gold? Understated, pretty, unique, reminds me of a peacock feather. Formula on this one was great to work with, opaque in two coats. I wonder how it compares to OPI's Here Today Aragon Tomorrow?
Starshine. I thought it was black in the bottle, but to my delight it is actually a dark, metallic, blue-toned anthracite with blue micro glitter. At first it just looks like the perfect dark metallic, kind of like one of Christian Louboutin's metal patent colors, but the blue glitter gives it even more depth and interest. The formula on this one was a bit watery, but not hard to work with (just be careful not to let it flood your cuticles). The first two coats were streaky but it evened out nicely with the third.
It's Electrifying is my favorite of the bunch (well, if I absolutely had to pick one)! It's an electric blue neon (yay!) with blue shimmer. Because it's a neon it dries to a satin finish, so you definitely need top coat to bring out the shimmer. It's bright and saturated at the same time and the shimmer gives it an extra dimension. This one applied nicely. You could actually get away with two coats if you don't mind visible nail line, but it turns out looking more teal than blue. Three coats are necessary to show the true color, and that is what I am wearing here.
Here are some comparisons.
Starshine next to Zoya Kotori:
Kotori has a darker base (that's not metallic) and a much more apparent blue shimmer. Kotori is also much sheerer.
Here's Orly Shine next to Moonsand:
As you can see, Shine is definitely brighter and it has closer to a chrome finish. Moonsand shows a little more texture because of the dark base.
Don't Teal My Heart Away next to Hypnotic:
Clearly, DTMHA is lighter in color and lacks the shimmer that Hypnotic has.
All of these colors are beautiful and unique, I have yet to be disappointed by Diamond Cosmetics! Part of the reason why I am posting this so late is because I really enjoyed wearing each color; I wasn't just swatching quickly like I do with some others (not that I don't love them too). For every color I can honestly say that I don't have anything else like it in my collection (although I don't have as many colors as some others). It's so refreshing as a winter collection, too; I love the mix of dark, bright, and metallic colors. It seems so appropriate for winter without being obvious (no holiday colors, no wintry whites). Drying time on these was a bit long; I would definitely recommend waiting a full 10-15 minutes between coats. Overall, though, I highly recommend all of them!
