Caracas (, Spanish: [kaˈɾakas]), officially Santiago de León de Caracas, abbreviated as CCS, is the capital and largest city of Venezuela, and the centre of the Metropolitan Region of Caracas (or Greater Caracas). Caracas is located across the Guaire River at the northern portion of the country, within the Caracas Valley of the Venezuelan coastal mountain range (Cordillera de la Costa). The valley is near the Caribbean Sea, separated from the coast by a steep 2,200-metre-high (7,200 ft) mountain range, Cerro El Ávila; to the south there are more hills and mountains. The Metropolitan Region of Caracas has an estimated population of almost 5 million inhabitants. The middle of the city remains Catedral, situated near Bolívar Square, although some consider the center to become Plaza Venezuela, located at the Los Caobos region.

Businesses in town include service companies, banks, and malls. Caracas has a mostly service-based market, besides some industrial action in its metropolitan area. The Caracas Stock Exchange and Petróleos de Venezuela (PDVSA) are headquartered in Caracas. PDVSA is the largest company in Venezuela. Caracas is also Venezuela's cultural capital, with many restaurants, theaters, museums, and shopping centers. Caracas has some of the tallest skyscrapers in Latin America, like the Parque Central Towers. The Museum of Contemporary Art of Caracas is one of the most important in South America.Caracas has among the highest per capita murder rates in the world, with 111.19 homicides per 100,000 inhabitants.

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.
