182 Metallic Blue. Bold blue shimmer. I don't know if I'd call this as metallic as much as I'd call it a frost- it is kind of frosty but not in the unflattering, brushstroke showing way. The color is bold and bright, sort of a medium blue shade that reminds me a bit of Essie Aruba Blue.
192 Hi-Ho Silver. Purple silver grey shimmer. This is a weak duochrome effect color, the duochrome is definitely there but it isn't dramatic or visible in all lighting. Just a nice, subtle change at different angles. Makes it interesting to look at. This is a little frosty as well, but not bad frosty, though brushstrokes are slightly visible when the polish is dry.
231 Party Hearty. Champagne foil. This is a really cool color. It's a champagne type color, not quite silver but not really gold either. Maybe white gold. Pale neutral. Party Hearty has a metallic foil finish that sparkles like it's on fire when it's outside. It gleams and glints, it shimmers and sparkles... It's super reflective and completely distracting.
232 Sparkling Sherry. Dark pink foil. This is a must have. I don't even like pink and I love this. It is too beautiful for words. The closest thing I can compare it to is Hard Candy Scam. It's the same type of foil metallic finish, but this one seems much more sparkly. This thing is insane. 
235 Decadence. Chocolate metallic foil. Noticing a trend here? Diamond Cosmetics does foils extremely well. They are rich and flashy and sparkle like crazy. This particular shade is a rich chocolate brown with hints of gold. I have a feeling I'll be wearing this a lot when the leaves start changing colors.
256 Seafoam Spray. Light seafoam green pearl. The color of Seafoam Spray is so pale and beautiful, it makes me feel relaxed looking at it. It's tranquil. Not the best color with my skin tone, but that won't stop me from wearing it. On top of the soft seafoam green base, there's an overlay of white pearl finish. It looks like the white is floating on top of the grean, and it looks smooth and pearly. So dreamy.
295 Hue Are You? Warm golden burgundy foil. Hey, look! Another foil! This one is different from the other ones, it's mostly a dark red burgundy base with gold flakes making the foil finish. The other foils seem like silver flakes with a colored sheer base that lets the silver shine through while adding tint. This shade screams fall to me. I love it.
302 Dirty and Flirty. Metallic taupe shimmer. The name of this one cracks me up. Taupe doesn't really scream dirty or flirty to me, but hey, maybe it does to someone! Anyway, beautiful smooth metallic pearl shimmer, borderline frosty. Nice soft color. Lots of sparkle.The formula on these was perfect. I had no application problems. The brushes were consistent and the texture of the polish was smooth and even. I applied all of these using the Diamond Cosmetics Base Coat and Quick Dry Topcoat. The basecoat provides an even yet sticky surface perfect for the polish to adhere to and the topcoat is smooth and glassy and is comparable to any good quick-dry on the market.
Since their online color chart is nameless and sort of nondescript as far as swatches go, you'll have to go by the numbers when ordering.
Diamond Cosmetics polishes retail for $2 each (excluding the neons, which are $2.50) and as far as I'm aware, can only be purchased from their website. Shipping is a flat rate of $4.95 for ten bottles or less, orders of more than ten bottles are charged exact shipping.
I still have more Diamond Cosmetics swatches to come :)
