Pearl vs Lahore

Informations

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.

Lahore (; Punjabi: لہور; Urdu: لاہور‎, pronounced [lɑːˈɦɔːr]) is the capital of the Pakistani province of Punjab, and is the country's 2nd largest city after Karachi, as well as the 18th largest city proper in the world. Lahore is one of Pakistan's wealthiest cities with an estimated GDP of $65.14 billion (PPP) as of 2017. Lahore is the largest city and historic cultural centre of the wider Punjab region, and is one of Pakistan's most socially liberal, progressive, and cosmopolitan cities.Lahore's origins reach into antiquity. The city has been controlled by numerous empires throughout the course of its history, including the Hindu Shahis, Ghaznavids, Ghurids, and Delhi Sultanate by the medieval era. Lahore reached the height of its splendour under the Mughal Empire between the late 16th and early 18th century, and served as its capital city for a number of years. The city was captured by the forces of the Afsharid ruler Nader Shah in 1739, and fell into a period of decay while being contested between the Afghans and the Sikhs. Lahore eventually became capital of the Sikh Empire in the early 19th century, and regained some of its lost grandeur. Lahore was then annexed to the British Empire, and made capital of British Punjab.

Lahore was central to the independence movements of both India and Pakistan, with the city being the site of both the declaration of Indian Independence, and the resolution calling for the establishment of Pakistan. Lahore experienced some of the worst rioting during the Partition period preceding Pakistan's independence. Following the success of the Pakistan Movement and subsequent independence in 1947, Lahore was declared capital of Pakistan's Punjab province. Lahore exerts a strong cultural influence over Pakistan. Lahore is a major center for Pakistan's publishing industry, and remains the foremost center of Pakistan's literary scene. The city is also a major centre of education in Pakistan, with some of Pakistan's leading universities based in the city. Lahore is also home to Pakistan's film industry, Lollywood, and is a major centre of Qawwali music. The city also hosts much of Pakistan's tourist industry, with major attractions including the Walled City, the famous Badshahi and Wazir Khan mosques and Sikh shrines. Lahore is also home to the Lahore Fort and Shalimar Gardens, both of which are UNESCO World Heritage Sites.
