Pearl vs Melbourne

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.

Melbourne ( (listen) MEL-bərn; Woiwurrung: Naarm) is the capital and most-populous city of the Australian state of Victoria, and the second-most populous city in Australia and Oceania. Its name refers to an urban agglomeration of 9,993 km2 (3,858 sq mi), comprising a metropolitan area with 31 municipalities, and is also a common name for its city centre. The city occupies much of the coastline of Port Phillip bay and spreads into the Hinterland towards the Dandenong and Macedon ranges, Mornington Peninsula and Yarra Valley. It has a population of 5 million (19% of the population of Australia), and its inhabitants are referred to as "Melburnians".Home to Indigenous Australians for over 40,000 years, the Melbourne area served as a popular meeting place for local Kulin nation clans. A short-lived penal settlement was established at Port Phillip, then part of the British colony of New South Wales, in 1803, but it was not until 1835, with the arrival of free settlers from Van Diemen’s Land (modern-day Tasmania), that Melbourne was founded. It was incorporated as a Crown settlement in 1837, and named Melbourne in honour of the then British Prime Minister, William Lamb, 2nd Viscount Melbourne. In 1851, four years after Queen Victoria declared it a city, Melbourne became the capital of the new colony of Victoria. In the wake of the 1850s Victorian gold rush, the city entered a lengthy boom period that, by the late 1880s, had transformed it into one of the world's largest and wealthiest metropolises.

After the federation of Australia in 1901, it served as the interim seat of government of the new nation until Canberra became the permanent capital in 1927. Today, it is a leading financial centre in the Asia-Pacific region and ranks 15th in the Global Financial Centres Index.Melbourne is home to many of Australia's best-known landmarks, such as the Melbourne Cricket Ground, the National Gallery of Victoria and the World Heritage-listed Royal Exhibition Building. Noted for its cultural heritage, the city gave rise to Australian rules football, Australian impressionism and Australian cinema, and has more recently been recognised as a UNESCO City of Literature and a global centre for street art, live music and theatre. It hosts major annual international events, such as the Australian Grand Prix and the Australian Open, and also hosted the 1956 Summer Olympics and the 2006 Commonwealth Games. Melbourne consistently ranked as the world's most liveable city for much of the 2010s.Melbourne Airport, also known as Tullamarine Airport, is currently not being used due to harsh travel restrictions, the city's port is the nation's busiest seaport. Its main metropolitan rail terminus is Flinders Street station and its main regional rail and road coach terminus is Southern Cross station. It also has Australia's most extensive freeway network and the largest urban tram network in the world.
