Rated 4 out of 5 by from Glamorous Glitter! Diamond theory just came in the mail today and I absolutely love it! The color is beautiful and it dries super quickly. It has the very bumpy glitter feel, but a top coat will help take some of the edge off. Totally recommend it <3

Rated 5 out of 5 by from My gateway to Julep glitters! The formula for this is thick (like most glitter polishes I presume), but I've worked with Nicole by OPI's glitters before so I don't get freaked out by those anymore haha. I only needed 2 coats for Diamond Theory to become opaque--& lemme tell you, this stuff sticks like glue! It got to a point where after 2 days I was trying to pick it off & it still wouldn't budge. So besides being an incredible copper color (which looks like money on my nails, & is ironically a great neutral!), this polish has the best staying power out of all my other glitters. I'll be getting a lot of use out of this :)

Rated 2 out of 5 by from Great finish but flaked off on almost all my nails I loved the look of this polish, It was bright and bold the only downside was I had to carry the bottle in my purse to do touch ups. I ended up touching up every single one of my nails a least once the day was over. Didnt have any extra wear on my nails and used a base coat and a top coat!

Rated 4 out of 5 by from Very pretty! This came in my maven box with the other Roc polishes and I am pretty pleased with it. It is hard to impress me with a glitter polish anymore because my collection of them is getting extensive but I really like the color of this one. It's coppery but not obnoxiously so. It looks more like champagne on me, I love it. I got great coverage with one coat and for no top coat, it's not that rough! I like this polish, very classy.
