I was seriously blown away when I saw this powder from Clé de Peau. "Inspired by the eternal allure of vintage jewelry," it boasts a multi-faceted jewel shape with a diamond-like sparkle. Even the box and outer case have the same design.

Since every store was sold out when I called around for this I wound up getting it through E-bay, but I maintain that it is well worth it. Definitely a holiday exhibition showstopper!
