Pearl vs Accra

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.

Accra (; Twi: Nkran; Dagbani: Ankara; Ga: Ga or Gaga) is the capital of Ghana covering an area of 225.67 km2 (87.13 sq mi) with an estimated urban population of 4.2 million as of 2020. It is organized into 12 local government districts – 11 municipal districts and the Accra Metropolitan District, which is the only district within the capital to be granted city status. "Accra" usually refers to the Accra Metropolitan Area, which serves as the capital of Ghana, while the district which is within the jurisdiction of the Accra Metropolitan Assembly is distinguished from the rest of the capital as the "City of Accra". In common usage, however, the terms "Accra" and "City of Accra" are used interchangeably. The intersection of the Lafa stream and Mallam junction serves as the western border of Accra, the Great Hall of the University of Ghana forms Accra's northern border, while the Nautical College forms the eastern border. The Gulf of Guinea forms the southern border. Formed from the merger of distinct settlements around British Fort James, Dutch Fort Crêvecoeur (Ussher Fort), and Danish Fort Christiansborg as Jamestown, Usshertown, and Christiansborg respectively, Accra served as the capital of the British Gold Coast between 1877 and 1957 and has since transitioned into a modern metropolis. The capital's architecture reflects this history, ranging from 19th-century colonial architecture to modern skyscrapers and apartment blocks.

Accra is the Greater Accra Region's economic and administrative hub, and serves as the anchor of the larger Greater Accra Metropolitan Area (GAMA), which is inhabited by about 4 million people, making it the thirteenth-largest metropolitan area in Africa. Strategic initiatives, such as transportation, are coordinated between the local government authorities, while the Accra Metropolitan Assembly, based in West Ridge, is responsible for the administration of the 60 km2 (23 sq mi) City of Accra only.Accra is the most densely populated city in Ghana. The central business district of Accra contains the city's main banks and department stores, as well as an area known as the Ministries, where Ghana's government administration is concentrated. Economic activities in Accra include the financial and commercial sectors, fishing, and the manufacture of processed food, lumber, plywood, textiles, clothing, and chemicals. Tourism is becoming a thriving source of business for those in arts and crafts, historical sites, and local travel and tour agents. The Oxford Street in the district of Osu has grown to become the hub of business and nightlife in Accra.In 2020, the Globalization and World Cities Research Network think tank designated Accra as a "Gamma -" level global city, indicating a growing level of international influence and connectedness.
