Have you seen these new Caviar Pearls manicure sets by Ciaté? Amazing! But it will only look good on long nails. These manicure sets retail for £18.00 (that includes 1 polish and the beads).
There are 3 colors to choose from: Rainbow, Mother of Pearl and Black Pearls. I think the black one is the prettiest.
I think you could totally recreate this Caviar look without these products. Check out PolishAholic's blog post.
