PEARLS. Native Americans of the Upper Mississippi River Valley were wearing pearls in necklaces and other ornaments when the early French explorers arrived. The pearls came from freshwater mussels or clams found in the Mississippi and other rivers and streams. (1)
The shape of a pearl is determined by its location in a shell. Those along the lip are round and are the most valuable. Wing-shaped pearls form along the back of the shell. Irregular pearls form in the heels of shells. Blister pearls, where the pearl is attached to the shell, are the most common. A good-sized irregular pearl can be found in about one in 100 clams. However, a good-sized, natural, round pearl occurs only once in every 10,000 clams. (2)
