Antwerp ( (listen); Dutch: Antwerpen [ˈɑntʋɛrpə(n)] (listen); French: Anvers [ɑ̃vɛʁs] (listen)) is a city in Belgium and the capital of Antwerp province in the Flemish Region. With a population of 520,504, it is the most populous city proper in Belgium, and with a metropolitan population of around 1,200,000 people, it is the second-largest metropolitan region after Brussels.Antwerp is on the River Scheldt, linked to the North Sea by the river's Westerschelde estuary. It is about 40 kilometres (25 mi) north of Brussels, and about 15 kilometres (9 mi) south of the Dutch border. The Port of Antwerp is one of the biggest in the world, ranking second in Europe and within the top 20 globally. The city is also known for its diamond industry and trade. In 2020, the Globalization and World Cities Research Network rated Antwerp as a Gamma + level Global City.

Both economically and culturally, Antwerp is and has long been an important city in the Low Countries, especially before and during the Spanish Fury (1576) and throughout and after the subsequent Dutch Revolt. The Bourse of Antwerp, originally built in 1531 and re-built in 1872, was the world's first purpose-built commodity exchange. It was founded before stocks and shares existed, so was not strictly a stock exchange.The inhabitants of Antwerp are nicknamed Sinjoren (Dutch pronunciation: [sɪɲˈjoːrə(n)]), after the Spanish honorific señor or French seigneur, "lord", referring to the Spanish noblemen who ruled the city in the 17th century. The city hosted the 1920 Summer Olympics.

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.
