Pearl vs Cheyenne

Informations

A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as fossil conulariids. Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable. The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as natural pearls. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of those currently sold.

Imitation pearls are also widely sold in inexpensive jewelry, but the quality of their iridescence is usually very poor and is easily distinguished from that of genuine pearls. Pearls have been harvested and cultivated primarily for use in jewelry, but in the past were also used to adorn clothing. They have also been crushed and used in cosmetics, medicines and paint formulations. Whether wild or cultured, gem-quality pearls are almost always nacreous and iridescent, like the interior of the shell that produces them. However, almost all species of shelled mollusks are capable of producing pearls (technically "calcareous concretions") of lesser shine or less spherical shape. Although these may also be legitimately referred to as "pearls" by gemological labs and also under U.S. Federal Trade Commission rules, and are formed in the same way, most of them have no value except as curiosities.

The Cheyenne ( shy-AN) are one of the indigenous people of the Great Plains whose language is of the Algonquian language family. The Cheyenne comprise two Native American tribes, the Só'taeo'o or Só'taétaneo'o (more commonly spelled as Suhtai or Sutaio) and the Tsétsêhéstâhese (also spelled Tsitsistas, [t͡sɪt͡shɪsthɑs]). These tribes merged in the early 19th century. Today, the Cheyenne people are split into two federally recognized Nations: the Southern Cheyenne, who are enrolled in the Cheyenne and Arapaho Tribes in Oklahoma, and the Northern Cheyenne, who are enrolled in the Northern Cheyenne Tribe of the Northern Cheyenne Indian Reservation in Montana. At the time of their first contact with the Europeans, the Cheyenne were living in the area of what is now Minnesota. At times they have been allied with the Lakota and Arapaho, and at other points enemies of the Lakota. In the early 18th century they migrated west across the Missouri River and into North and South Dakota, where they adopted the horse culture. Having settled the Black Hills of South Dakota and the Powder River Country of present-day Montana, they introduced the horse culture to Lakota bands about 1730. Allied with the Arapaho, the Cheyenne pushed the Kiowa to the Southern Plains. In turn, they were pushed west by the more numerous Lakota.The Cheyenne Nation or Tsêhéstáno was at one time composed of ten bands that spread across the Great Plains from southern Colorado to the Black Hills in South Dakota.

They fought their traditional enemies, the Crow and later (1856–79) the United States Army forces. In the mid-19th century, the bands began to split, with some bands choosing to remain near the Black Hills, while others chose to remain near the Platte Rivers of central Colorado. The Northern Cheyenne, known in Cheyenne either as Notameohmésêhese, meaning "Northern Eaters" or simply as Ohmésêhese meaning "Eaters", live in southeastern Montana on the Northern Cheyenne Indian Reservation. Tribal enrollment figures, as of late 2014, indicate that there are approximately 10,840 members, of which about 4,939 reside on the reservation. Approximately 91% of the population are Native Americans (full or part race), with 72.8% identifying themselves as Cheyenne. Slightly more than one quarter of the population five years or older spoke a language other than English.The Southern Cheyenne, known in Cheyenne as Heévâhetaneo'o meaning "Roped People", together with the Southern Arapaho, form the Cheyenne and Arapaho Tribes, in western Oklahoma. Their combined population is 12,130, as of 2008. In 2003, approximately 8,000 of these identified themselves as Cheyenne, although with continuing intermarriage it has become increasingly difficult to separate the tribes.
