Tennessee State Gemstone or Gem

Tennessee Pearl

CaCO3 - Calcium Carbonate

Adopted in 1979.

The pearl, CaCO3 - Calcium Carbonate, taken from mussels in the fresh water rivers of the state, is the official state gem, as designated by 1979 Public Chapter 192 of the 91st General Assembly.

Native Americans of the Atlantic Coastal areas and the Mississippi River Basin were the first to collect and use US freshwater mussel pearls and shells. Pearl pendants and ear pendants were worn by both sexes and both pearl and shell were used for decorative purposes on articles of clothing. Some of the tribes used pearls as tributes, reportedly Powhattan (Pocahontas' father) had large stores of pearls received as tribute. These shellfish served as an important supplemental food resource, while the shells themselves were often modified into various tools, such as scrapers and "hoes," bowls and "spoons," and ornaments. Additionally, armlets, pendants, and gaming pieces were made from mussel shell.

During the years between 1882 and 1914, beautiful pearls were taken from many of the state's streams, from the Pigeon and Holston in the east to the Forked Deer and Obion in the west. The Caney Fork in Middle Tennessee was noted for its pearl-bearing mussels, and "pearling" was a favorite sport for young people on Sunday afternoons at the turn of the century.

Natural freshwater pearls are seldom perfectly round or even nearly round, more often than not they are baroque, slugs, or wings. Many pearls, both natural and cultured, have beautiful color and luster. Freshwater pearls are noted for their wide range of color, they can be found in white, silvery white, pink, salmon, red, copper, bronze, brown, lavender, purple, green, blue, cream, and yellow. Although white is the most common color, the most desirable are the pastel pinks, roses, lavenders, and purples. The different colors are a function of the mussel species, genetics, water quality, and the position of the pearl in the shell. Generally, pearls assume the color of the shell in which they form. Problems can arise in putting together matched strands because of the wide range of pastel colors.

Tennessee river pearls are of all colors and they are "natural" as the mussel made them—all pearl, all the way through. They have been found in various shapes—spherical, pear-shaped, and baroque or irregular. After World War I, dams were built on many of the rivers, and the mussels lost their swift and shallow shoals. Also, the waters became more toxic and pearling became unprofitable.

The first experimental US freshwater cultured pearl farm was established in Tennessee by John Latendresse in 1963. Latendresse is the father of US cultured freshwater pearls, having spent nearly 30 years and more time, money, and effort than anyone else in the research and development of the industry. Since proving the technology for culturing freshwater pearls in the late 1970's, Mr. Latendresse has established five freshwater pearl farms. James Peach, who once worked with Latendresse, has established a single farm. Additionally, a single farm has been established in California using mussels from the Southeastern United States. These farms are the foundation of the US freshwater cultured pearl industry, and the cultured pearl is the heart and future of the US pearl industry.

Today, pearling exists as a byproduct of shell harvests which supply the cultivated pearl industry of Japan. Tennessee river pearls are among the most beautiful and durable in the world. At Camden in West Tennessee, these river pearls are collected and crafted into rings, cuff links, stick pins, and other jewelry. Tennessee River Pearls
