I've never worn black nail varnish but this sparkly "Cosmic" Eyeko nail polish I was sent is gorgeous. It will only last one night though as it chips easily.
The pictures below are two coats over a clear base coat.
One tip to protect your cuticles and skin getting stained is to use the first coat to shape the varnish. Shape it so that it does not touch the sides or nail bed. The second coat to deepen the colour.
I can't stop admiring these, as night falls the multicoloured glitter comes alive!
