This isn't a polish you can buy, but I just wanted to share it, because it's so pretty! It was made for me by a lovely friend, Ida, who has a super blog, Ida Nails It. If you don't already, you should check out her super nails and pictures :D
The polish is called 'Alison's Purple Sky' and it's a stunning purple with small magenta glitter. I'll just let the pictures do the talking!
