The Guggenheim Museum turns 50 years old next year and you can now own a little piece of the iconic building. The building has been undergoing a massive restoration, and lightweight concrete and Gunite remnants were set aside and are now being showcased in...jewelry! From the press release:

[Jewelry artist Cara] Tilker makes each jewelry piece through a labor-intensive process. Resin is poured into a handmade silicone rubber mold, then individual building fragments are placed in the resin, covered with a second layer of resin and allowed to set. After the resin pieces are released from the mold, they are hand-shaped and sanded, and finally set in sterling silver settings.
