A black acrylic nail worn by performer Lady Gaga during her "Born This Way Ball" tour and designed by Aya Fukuda is being auctioned for at least $712. A member of the stage crew for her concert in Dublin, Ireland on Sept. 15, 2012 listed the item. The seller said in the listing: "As I was about to start work I noticed an object on the floor of the stage, which at first I thought was a guitar plectrum. When I picked it up, I saw it was an acrylic nail." The auction closes on May 30, 2013.
