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.

Limoges (, also US: , French: [limɔʒ] (listen); Occitan: Lemòtges, locally Limòtges [liˈmɔdzes]) is a city and commune, the capital of the Haute-Vienne department and was the administrative capital of the former Limousin region in west-central France. Situated on the first western foothills of the Massif Central, Limoges is crossed by the Vienne River, of which it was originally the first ford crossing point.
The second most populated town in the New Aquitaine region after Bordeaux, a university town, an administrative centre and intermediate services with all the facilities of a regional metropolis, its has an urban area of 283,557 inhabitants in 2016, making it the sixth in South-West France and the 38th in the whole country.The inhabitants of the city are called the Limougeauds.
Founded around 10 BC under the name of Augustoritum, it became an important Gallo-Roman city. In the Middle Ages Limoges becomes a large city, strongly marked by the cultural influence of the Abbey of Saint-Martial, within the Duchy of Aquitaine, whose dukes are invested and crowned in this city. From the 12th century onwards, its enamels were exported throughout the Christian world. In 1765, during the industrial revolution, the discovery of a deposit of kaolin in the Saint-Yrieix-la-Perche region enabled the development of the Limoges porcelain industry, which would make Limoges world-famous.
