Finders Keepers: Artist Hides 7 Diamonds in Exhibit Today is the last day, so hurry on over By Evann Gastaldo, Newser Staff Posted Nov 30, 2013 12:33 PM CST 8 comments Comments (Shutterstock) (Newser) – Well, this is one way to get people to come to your exhibition: For the last week of his "Bouncing Cars" installation at New York's Ambassador Gallery, Jamison Ernest hid a diamond a day somewhere in the exhibit, the Wall Street Journal reports. Whoever finds that day's diamond keeps it—and you'd better hurry over if you want to try, because today is the last day. "I've always hoped that somebody who needed it would find it," the Brooklyn artist says. "But it's about appreciating the value of the challenge." Ernest partnered with Phantom Luxury Group to make the diamond "scavenger hunt" happen; the seven jewels are worth $77,777 total. "I want to give people hope," Ernest explains to Examiner.com. As for all those 7s, he explains, "Great foundations are built with the number 7."
