I finally got my hands on Facet! It's one of those polishes that is so lovely is deserves it's own post. Lots of pictures ahead (warning: it will make you want to buy it!)
Described as "Grey Crystal" on the website, Facet is part of Illamasqua's Sacred Hour collection. It's a grey/taupe base packed full of coppery shimmer flakes, and is completely stunning! It's simple yet still somehow unique in my stash. I think Raindrops will always be my favourite Illamasqua shade, but this comes very very close. I love having an Illamasqua shop readily available to me...every time I go in I want to melt into a puddle on the floor!
The formula is buttery good, I've used 2 coats plus top coat in my swatches.
