Truth is sometimes stranger than fiction. These gorgeous shells, on display at the Smithsonian Castle, are similar to intricate jewelry. They are part of the exhibit The Smithsonian Institution, America's Treasure Chest.I urge you all to visit the historic Smithsonian castle and check out the treasures of the institution! And just to accompany these gorgeous shells, a gorgeous voice singing about the fishes in the sea....Nina Simone, Feeling Good
