Calling all you nail geniuses (genii?) Can anyone recommend an iridescent topcoat?

[MsOliveOyl]

I'm looking for a sparkly iridescent polish in a clear base that I can paint over other colours, but have never bought anything like that so don't know where to start!

China glaze fairy dust

PERFECT! Thank you :) Just been looking at reviews on MUA and it's exactly what I was looking for.

Try the Orly range of sparkling glitters - there is one with clear base and tiny sparkly particles, I have it in my hand but it has no name on it.

The new Revlon colourstay range has a whitish one with pinkish iridescence called Calla Lily

Thanks Pelicano, will have a look in Boots tomorrow, they seem to do Orly now.

I actually found one on my way home today - it was in the window of a nail bar run by a Filippino family and they have loads of interesting polishes from Asia. It's by Nfu Oh and the glitter is larger than I wanted (it's like flakies mixed in with glitter), but the rainbow sparkliness and application is great.

I layered it over Essie carousel coral and I can't decide if it looks amazing or like a Barbie has puked on my nails

GOSH Rainbow here not my nails!
