Whenever I buy new jewelry, I consider it art, but this really takes it to a whole new level. The Guggenheim Museum's releasing a line of jewelry in honor of their 50th anniversary. Everything in the collection - including necklaces, bracelets, cuff links and earrings - is made out of Gunite remnants from the original Frank Lloyd Wright building. The rough rocks have been embedded in resin and set in sterling silver. California-based artist Cara Tilker designed the collection, called Restoration Rocks, and prices start at $80. You can buy it online or at the museum store. We'd suggest swinging by on October 21st - admission to the museum's free so you can enjoy the collection and put your $18 toward a ring instead.
