Empress Of Uruguay
The Empress of Uruguay is the world's largest amethyst geode, standing at a height of 3.27 meters. It is open along its length and weighs 2.5 tons in its current state. It was discovered in 2007 in the Artigas department, Uruguay by the Uruguayan mining company Le Stage Minerals. Its estimated value is US $190,000, although it is not for sale. Background The geode was found in a mine near the city of Artigas, known for its spectacular geodes and amethysts. It was extracted from the surrounding basalt in a complicated process that took three months. The top part was cut to allow for a view of the interior and the amethyst crystals that were on the top were sold. The decision was made to leave the majority of the geode intact for exhibition purposes. It is part of a travelling exhibition and has been on display at the American Museum of Natural History The American Museum of Natural History (abbreviated as AMNH) is a natural history museum on the Upper West Side of Manhatt ...

Artigas Department
Artigas Department ( es, Departamento de Artigas, ) is the northernmost department of Uruguay, located in its northwestern region. Its capital is the city of Artigas, which borders on the Brazilian city of Quaraí. Artigas Department has an area of , making it the fifth largest in the country. The population is 73,378 inhabitants, according to the 2011 census. It is bordered on the north and east by Brazil, from which it is separated by the Cuareim River. To the south, Artigas Department borders on Salto Department, and to the west is Argentina, from which it is separated by the Uruguay River. Artigas is the only Uruguayan department that borders two other countries. The department and its capital city are named after José Gervasio Artigas (1764–1850), leader of the ''Orientales'' (inhabitants of the ''Banda Oriental'', the Eastern bank of the Uruguay River) during Uruguay's wars of independence.

Uruguay
Uruguay (; ), officially the Oriental Republic of Uruguay ( es, República Oriental del Uruguay), is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast; while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately and has a population of an estimated 3.4 million, of whom around 2 million live in the metropolitan area of its capital and largest city, Montevideo. The area that became Uruguay was first inhabited by groups of hunter–gatherers 13,000 years ago. The predominant tribe at the moment of the arrival of Europeans was the Charrúa people, when the Portuguese first established Colónia do Sacramento in 1680; Uruguay was colonized by Europeans late relative to neighboring countries. The Spanish founded Montevideo as a military stronghold in the early 18th century bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artigas, Uruguay
Artigas () is the capital of the Artigas Department of Uruguay. Its name comes from that of the national hero, José Gervasio Artigas, who fought for the emancipation of the River Plate, and sought to create a federative nation from these colonies. As of the census of 2011, it is the eleventh most populous city in the country. Location The city is located on the border with Brazil, separated only by a bridge from the town Quaraí of the state Rio Grande do Sul of Brazil. It is the farthest city from Uruguay's capital Montevideo, being away. History It was founded on 12 September 1852 by Don Carlos Catalá as the town of San Eugenio del Cuareim. On 5 September 1884 it became capital of the department. It was renamed Artigas and its status was elevated from ''villa'' (town) to ''ciudad'' (city) on 31 August 1915. Economy Artigas is a centre for trading grain crops (primarily maize) with Argentina and Brazil. The railroad station and, since 1973, airport are focused on this comme ...

Geode
A geode (; ) is a geological secondary formation within sedimentary and volcanic rocks. Geodes are hollow, vaguely spherical rocks, in which masses of mineral matter (which may include crystals) are secluded. The crystals are formed by the filling of vesicles in volcanic and subvolcanic rocks by minerals deposited from hydrothermal fluids; or by the dissolution of syn-genetic concretions and partial filling by the same or other minerals precipitated from water, groundwater, or hydrothermal fluids. Formation Geodes can form in any cavity, but the term is usually reserved for more or less rounded formations in igneous and sedimentary rocks. They can form in gas bubbles in igneous rocks, such as vesicles in basaltic lava; or, as in the American Midwest, in rounded cavities in sedimentary formations. After rock around the cavity hardens, dissolved silicates and/or carbonates are deposited on the inside surface. Over time, this slow feed of mineral constituents from groundwater o ...

Amethyst
Amethyst is a violet variety of quartz. The name comes from the Koine Greek αμέθυστος ''amethystos'' from α- ''a-'', "not" and μεθύσκω (Ancient Greek) / μεθώ (Modern Greek), "intoxicate", a reference to the belief that the stone protected its owner from drunkenness. Ancient Greeks wore amethyst and carved drinking vessels from it in the belief that it would prevent intoxication. Amethyst, a semiprecious stone, is often used in jewelry and is the traditional birthstone for February. Structure Amethyst is a purple variety of quartz (SiO2) and owes its violet color to irradiation, impurities of iron and in some cases other transition metals, and the presence of other trace elements, which result in complex crystal lattice substitutions.Michael O'Donoghue (2006), ''Gems'', Butterworth-Heinemann, 6th ed. The hardness of the mineral is the same as quartz, thus making it suitable for use in jewelry. Hue and tone Amethyst occurs in primary hues from a li ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Mining In Uruguay
The mining sector contributes only 0.1% to the GDP of Uruguay. Uruguay's mineral commodities include clays, semiprecious gemstones, gold, iron and steel, sand and gravel, and stone. Uruguay has no proven natural gas or oil reserves but it does have substantial hydroelectric capacity.Gurmendi, Alfredo C"The Mineral Industry of Paraguay and Uruguay"(PDF). ''2006 Minerals Yearbook''. United States Geological Survey (April 2008) . Structure of the Mineral Industry The mineral industry of Uruguay mostly consisted of Uruguayan state-owned firms. The structure of the country's mineral industry could change to a privately owned, government-regulated regime from one that was government owned and government operated. Foreign direct investment (FdI) inflows to Mercosur had a positive effect on Uruguay's FdI inflows, which increased to $1.4 billion in 2006 from $847.4 million in 2005, and that mostly reflected the high international prices of several commodities, such as cement, steel, s ...

Individual Gemstones
An individual is that which exists as a distinct entity. Individuality (or self-hood) is the state or quality of being an individual; particularly (in the case of humans) of being a person unique from other people and possessing one's own needs or goals, rights and responsibilities. The concept of an individual features in diverse fields, including biology, law, and philosophy. Etymology From the 15th century and earlier (and also today within the fields of statistics and metaphysics) ''individual'' meant " indivisible", typically describing any numerically singular thing, but sometimes meaning "a person". From the 17th century on, ''individual'' has indicated separateness, as in individualism. Law Although individuality and individualism are commonly considered to mature with age/time and experience/wealth, a sane adult human being is usually considered by the state as an "individual person" in law, even if the person denies individual culpability ("I followed ...
