Facebook is the place for indie polish to thrive these days. Every brand has a fan group, designed to be a place to share info, trade, and post your manicure pictures. As a "thank you" to the tight-knit groups, many brands offer exclusive shades just for the members. Few brands have more stunning customs than Baroness X.

Anthracite is a midnight navy jelly filled with the majestic Unicorn Pee, copper shimmer, and twinkling with holo. Imagine if you could paint the night sky with UP...and then bottle it up. This is what you'd end up with. Baroness X does jellies oh so right, and this shade is no different. It applies fully opaque in three coats, and I followed it with a layer of Seche Vite for a glossy look. I love the depth that this polish has, and I definitely want to wear it forever. Or at least for a few days.
This polish is currently not available, but I would encourage you to join the fangroup on Facebook. You never know what goodies might pop up in there.
