Pearl vs Canberra

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.

Canberra ( (listen) KAN-bə-rə)

is the capital city of Australia. Founded after the federation of the colonies of Australia as the seat of government for the new nation, it is Australia's largest inland city and the eighth-largest town overall. The city is located at the northern end of the Australian Capital Territory; 280 km (170 mi) south-west of Sydney and 660 km (410 mi) north-east of Melbourne. On 1 January 1901, federation of the colonies of Australia has been attained. Section 125 of the new Australian Constitution provided that property, situated in New South Wales and at least 100 miles (160 km) from Sydney, would be ceded to the new national government. Following discussion and exploration of various areas within New South Wales, the Seat of Government Act 1908 was passed in 1908 that given a capital in the Yass-Canberra area. The land has been transferred to the Commonwealth by New South Wales in 1911, producing the Australian Capital Territory, two years prior to the capital city being founded and formally named as Canberra in 1913. It is unusual among Australian cities, being an entirely planned city beyond any state, like Washington, D.C. in america or Brasília in Brazil. Following an international contest for the city's layout, a blueprint by American architects Walter Burley Griffin and Marion Mahony Griffin was selected and building began in 1913. The Griffins' plan featured geometric themes such as circles, hexagons and triangles, and has been centred on axes aligned with significant topographical landmarks in the Australian Capital Territory. The town's design was influenced by the garden city movement and incorporates significant areas of natural vegetation. Since the chair of the government of Australia, Canberra is home to many important institutions of the national government, national monuments and museums. This includes Parliament House, the official residence of the monarch's representative that the Governor-General, the High Court and numerous government departments and agencies.



It is also the location of many social and cultural institutions of national significance like the Australian War Memorial, the Australian National University, the Royal Australian Mint, the Australian Institute of Sport, the National Gallery, the National Museum and the National Library. The town is also home to many important institutions of the Australian Defence Force including the Royal Military College Duntroon and the Australian Defence Force Academy. Additionally, it hosts the majority of foreign embassies in Australia as well as regional headquarters of numerous international organisations, non-profit groups, lobbying groups and professional associations. Canberra doesn't have a local council or town government like other Australian cities. The Australian Capital Territory Legislative Assembly performs the roles of both a town council for the town and a territory government for the rest of the Australian Capital Territory. The huge majority of the populace of the Territory reside in Canberra though and the town is therefore the primary focus of the ACT Government. However, the federal government maintains jurisdiction over the Territory and may overturn local laws. It still maintains control over the area known as the Parliamentary Triangle through the National Capital Authority. As at June 2019 the population of Canberra was 426,704, having increased by 1.5% over the previous 12 months. Since the city has a high percentage of public servants, the Commonwealth Government contributes the largest proportion of gross territory product and is the biggest single employer in Canberra, but not the majority employer. In comparison to the national averages, the unemployment rate is lower and the average income greater; tertiary education levels are higher, while the population is younger.
