I have done just one coat on each of the swatches above and as you can see they leave a very lovely first coat, I especially like Pearly Queen. These make a very lovely feature nail alongside a matte colour, I would definitely recommend around 2-3 coats for the full pearlescent effect.
They seem to last for a very long time without chipping or fading on the nail, I found this really impressive as I work on a computer all day.

Will definitely be purchasing the rest of this collection! (My nail polish sets are getting out of hand now...)
