Belfast vs Pearl

Informations

Belfast ( BEL-fahst; from Irish: Béal Feirste, meaning "mouth of the sand-bank ford", Irish pronunciation: [bʲeːlˠ ˈfʲɛɾˠ(ə)ʃtʲə]) is the capital and largest city of Northern Ireland, standing on the banks of the River Lagan on the east coast. It is the 12th-largest city in the United Kingdom and the second-largest on the island of Ireland. It had a population of 333,871 as of 2015. Belfast suffered greatly in the Troubles: in the 1970s and 1980s it was one of the world's most dangerous cities, with a homicide rate around 31 per 100,000.By the early 19th century, Belfast became a major port. It played an important role in the Industrial Revolution in Ireland, becoming briefly the biggest linen-producer in the world, earning it the nickname "Linenopolis". By the time it was granted city status in 1888, it was a major centre of Irish linen production, tobacco-processing and rope-making.

Shipbuilding was also a key industry; the Harland and Wolff shipyard, which built the RMS Titanic, was the world's largest shipyard. Belfast as of 2019 has a major aerospace and missiles industry. Industrialisation, and the inward migration it brought, made Belfast Northern Ireland's biggest city. Following the partition of Ireland in 1922, Belfast became the seat of government for Northern Ireland. Belfast's status as a global industrial centre ended in the decades after the Second World War. Belfast is still a port with commercial and industrial docks, including the Harland and Wolff shipyard, dominating the Belfast Lough shoreline. It is served by two airports: George Best Belfast City Airport and Belfast International Airport 15 miles (24 km) west of the city. The Globalization and World Cities Research Network (GaWC) listed Belfast as a Gamma + global city in 2020.

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.
