A very pretty glitzy glam nail varnish from Rimmel called Diamond Dust. They also do a red version of this which if I remember correctly is called Ruby Crush. It is just purely glitter in a mixture of sizes and shapes. It took three coats to get to this opacity and then I put a shine top coat on to really show the bling of it. Only downside is that it was an absolute bugger to get off as with most glitters.
