Valencia vs Pearl

Informations

Valencia (Spanish: [baˈlenθja]), officially València (Valencian: [baˈlensia] (locally) or [vaˈlensia]), is the capital of the autonomous community of Valencia and the third-largest city in Spain after Madrid and Barcelona, surpassing 800,000 inhabitants in the municipality. The wider urban area also comprising the neighbouring municipalities has a population of around 1.6 million. Valencia is Spain's third-largest metropolitan area, with a population ranging from 1.7 to 2.5 million depending on how the metropolitan area is defined. The Port of Valencia is the 5th-busiest container port in Europe and the busiest container port on the Mediterranean Sea. The city is ranked as a Gamma-level global city by the Globalization and World Cities Research Network.Valencia was founded as a Roman colony by the consul Decimus Junius Brutus Callaicus in 138 BC and called Valentia Edetanorum. In 714, Moroccan and Arab Moors occupied the city, introducing their language, religion and customs; they implemented improved irrigation systems and the cultivation of new crops as well. Valencia was the capital of the Taifa of Valencia. In 1238 the Christian king James I of Aragon conquered the city and divided the land among the nobles who helped him conquer it, as witnessed in the Llibre del Repartiment.

He also created the new Kingdom of Valencia, which had its own laws (Furs), with Valencia as its main city and capital. In the 18th century Philip V of Spain abolished the privileges as punishment to the kingdom of Valencia for aligning with the Habsburg side in the War of the Spanish Succession. Valencia was the capital of Spain when Joseph Bonaparte moved the Court there in the summer of 1812. It also served as the capital between 1936 and 1937, during the Second Spanish Republic. The city is situated on the banks of the Turia, on the east coast of the Iberian Peninsula, fronting the Gulf of Valencia on the Mediterranean Sea. Its historic centre is one of the largest in Spain, with approximately 169 ha (420 acres). Due to its long history, Valencia has numerous celebrations and traditions, such as the Fallas, which were declared Fiestas of National Tourist Interest of Spain in 1965 and an Intangible cultural heritage by UNESCO in November 2016. Joan Ribó from Compromís has been the mayor of the city since 2015.

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.
