When you're not near a light all of the little diamonds just look like a nice light rose/pink color, but under a light or in the sun they really sparkle and reflect different colors.
To test the glitter out I did a glitter border manicure. The polish I used for the base of this manicure is Sonia Kashuk Lacquered Lilac.
The glitters were surprisingly easy to place, I imagine it would be quite time consuming to attempt and cover your entire nail, but to do the border it was quite a quick process. I used a dotting tool and a bit of top coat to pick up each piece of glitter and then pressed it down, just like I do with other glitters or any of the studs I've tried.
I really like this glitter, I can see it becoming another of my favorite nail art decoration items, and I'll have a lot of fun thinking of different ways to incorporate it into manicures.
The diamond glitters are $2.38 and you can still use my 10% off code, BRJ61 for anything off of BPS!
