Pearl vs Barranquilla

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.

Barranquilla (American Spanish: [baraŋˈkiʝa] (listen)) is the capital district of Atlántico Department in Colombia. It is located near the Caribbean Sea and is the largest city and second port in the northern Caribbean Coast region; as of 2018 it had a population of 1,206,319 making it Colombia's fourth-most populous city after Bogotá, Medellín and Cali. Barranquilla lies strategically next to the delta of the Magdalena River, 7.5 kilometres (4.7 miles) (originally 25 kilometres (16 miles) before rapid urban growth) from its mouth at the Caribbean Sea, serving as a port for river and maritime transportation within Colombia. It is also the main industrial, shopping, educational and cultural center of the Caribbean Region of Colombia. The city is the core of the Metropolitan Area of Barranquilla, with a population of over 2 million, which also includes the municipalities of Soledad, Galapa, Malambo, and Puerto Colombia. Barranquilla was legally established as a town on April 7, 1813, although it dates from at least 1629. It grew into an important port, serving as a haven for immigrants from Europe, especially during and immediately following World War I and World War II, when waves of additional immigrants from the Middle East and Asia arrived.

Barranquilla became Colombia's principal port, and with its level of industrialization and modernity earned the city the nickname "Colombia's Golden Gate" (Spanish: La Puerta de Oro de Colombia). In the 1940s, Barranquilla was the second-largest city in Colombia and one of the most modern cities in the Caribbean and in South America; later local administrations, due to widespread corruption in their ranks, brought about a decline in the standard of living. As government investment increased in other Colombian cities, Barranquilla's national position was eclipsed. The city is home to one of the most important folk and cultural festivals of Colombia, the Carnival of Barranquilla, which was declared a National Cultural Heritage by the Congress of Colombia in 2001 and recognized by UNESCO in 2003.Ernesto Cortissoz International Airport, built in Barranquilla in 1919, was the first airport in South America. The city is served by domestic and international flights.
