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.

Aarhus (, also US: , Danish: [ˈɒːˌhuˀs] (listen); officially spelled Århus from 1948 until 1 January 2011) is the second-largest city in Denmark and the seat of Aarhus municipality. It is located on the east coast of the Jutland peninsula, in the geographical centre of Denmark, 187 kilometres (116 mi) northwest of Copenhagen and 289 kilometres (180 mi) north of Hamburg, Germany. The inner urban area contains 280,534 inhabitants (as of 1 January 2020) and the municipal population is 349,983 (as of 2020). Aarhus is the central city in Business Region Aarhus and in the East Jutland metropolitan area, which had a total population of 1.378 million in 2016.The history of Aarhus began as a fortified Viking settlement founded in the 8th century and with the first written records stemming from the bishopric seated here from at least 948. The city was founded on the northern shores of a fjord at a natural harbour and the primary driver of growth was for centuries seaborne trade in agricultural products. Market town privileges were granted in 1441, but growth stagnated in the 17th century as the city suffered blockades and bombardments during the Swedish Wars. In the 19th century it was occupied twice by German troops during the Schleswig Wars but avoided destruction. As the industrial revolution took hold, the city grew to become the second-largest in the country by the 20th century.
Today, Aarhus is at the cultural and economic core of the region and the largest centre for trade, services, industry, and tourism in Jutland.
