Elizabeth Arden Pure Finish Highlighter in Rose Illumination. It was part of their Spring/Summer collection and was selling out like hot cakes. I'm not sure if they've made it permanent but they have certainly restocked and it is available on their website. Plus, through tomorrow, you can get 30% off the site and free shipping over $40 (if you go through Mr. Rebates, you'll also get yourself 6% cash back). I haven't found this 30% anywhere other than Mr. Rebates as you'll see it as an option with the link (but no code), though there is a 25% off code RMN25 available.
Disclosure: Referral link.
