Toulouse ( too-LOOZ, French: [tuluz] (listen); Occitan: Tolosa [tuˈluzɔ]; Latin: Tolosa [tɔˈloːsa]) is the capital of the French department of Haute-Garonne and of the region of Occitanie. The city is on the banks of the River Garonne, 150 kilometres (93 miles) from the Mediterranean Sea, 230 km (143 mi) from the Atlantic Ocean and 680 km (420 mi) from Paris. It is the fourth-largest city in France, with 479,553 inhabitants within its municipal boundaries (as of January 2017), and 1,360,829 inhabitants within its wider metropolitan area (also as of January 2017), after Paris, Lyon and Marseille, and ahead of Lille and Bordeaux. Toulouse is the centre of the European aerospace industry, with the headquarters of Airbus (formerly EADS), the SPOT satellite system, ATR and the Aerospace Valley. It also hosts the European headquarters of Intel and CNES's Toulouse Space Centre (CST), the largest space centre in Europe. Thales Alenia Space, ATR, SAFRAN, Liebherr-Aerospace and Airbus Defence and Space also have a significant presence in Toulouse. The University of Toulouse is one of the oldest in Europe (founded in 1229) and, with more than 103,000 students, it is the fourth-largest university campus in France, after the universities of Paris, Lyon and Lille.

The air route between Toulouse–Blagnac and the Paris airports is the busiest in France, transporting 3.2 million passengers in 2019. According to the rankings of L'Express and Challenges, Toulouse is the most dynamic French city.Founded by the Romans, the city was the capital of the Visigothic Kingdom in the 5th century and the capital of the province of Languedoc in the Late Middle Ages and early modern period (provinces were abolished during the French Revolution), making it the unofficial capital of the cultural region of Occitania (Southern France). It is now the capital of the Occitanie region, the second largest region in Metropolitan France. Toulouse counts three UNESCO World Heritage Sites: the Canal du Midi (designated in 1996 and shared with other cities), and the Basilica of St. Sernin, the largest remaining Romanesque building in Europe, designated in 1998 along with the former hospital Hôtel-Dieu Saint-Jacques because of their significance to the Santiago de Compostela pilgrimage route. The city's unique architecture made of pinkish terracotta bricks has earned Toulouse the nickname La Ville Rose ("The Pink City").

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.
