Here's a nice close-up of the bottle from Daily Varnish.
Re availability: not a current color, although it still has a page on SC's website. (On Amazon it's anywhere from $4 to $40, at the moment.) It was a holiday polish so it may have been LE in the first place.
(Added: this is in my top 5 Sinful Colors polishes, and I swatched it there over red, which it turns out I quite like. This was also in my 2014 favorites.)
