The Frank Gehry 7-Fish necklace is a $1,500 piece of art that you can own for your neck. The fish are made of sterling silver, onyx, nephrite green jade, acacia wood, and pernambuco. Interestingly, the copyrighted design is sparking some controversy. While Tiffany & Co is currently selling the necklace, Circa Publishing Enterprises is suing for half the proceeds, claiming it had exclusive rights to market and produce the necklace.
