Smoky Quartz
Smoky quartz is a brownish grey, translucent variety of quartz that ranges in clarity from almost complete transparency to an almost-opaque brownish-gray or black crystals. The smoky color results from free silicon formed from the silicon dioxide by natural irradiation. Varieties Morion is a very dark brown to black opaque variety. Morion is the German, Danish, Spanish and Polish synonym for smoky quartz. The name is from a misreading of ''mormorion'' in Pliny the Elder. Cairngorm is a variety of smoky quartz found in the Cairngorm Mountains of Scotland. It usually has a smoky yellow-brown colour, though some specimens are greyish-brown. It is used in Scottish jewellery and as a decoration on kilt pins and the handles of (anglicised: ''sgian-dubhs'' or ''skean dhu''). The largest known cairngorm crystal is a specimen kept at Braemar Castle. Uses Smoky quartz is common and was not historically important, but in recent times it has become a popular gemstone, especially for je ...

Silicate Minerals
Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of Earth's crust. In mineralogy, silica (silicon dioxide, ) is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphs. On Earth, a wide variety of silicate minerals occur in an even wider range of combinations as a result of the processes that have been forming and re-working the crust for billions of years. These processes include partial melting, crystallization, fractionation, metamorphism, weathering, and diagenesis. Living organisms also contribute to this geologic cycle. For example, a type of plankton known as diatoms construct their exoskeletons ("frustules") from silica extracted from seawater. The frustules of dead diatoms are a major constituent of deep ocean sediment, and of diatomaceous earth. General structure A silicate mineral is general ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Metazeunerite
Metazeunerite is an arsenate mineral with a chemical formula of Cu(UO2)2(AsO4)2·8H2O. The origin of this mineral is almost always from the natural dehydration process of zeunerite. Named for civil engineer Gustav A. Zeuner who worked at the School of Mines in Freiberg and its lowered hydration state. Properties Its crystal system is tetragonal and its crystal class is 4/m, which is also called the tetragonal-dipyramidal class because it only has a vertical four-fold rotation axis that is perpendicular to the symmetry plane. When looking at a thin section, metzeunerite is anisotropic, meaning that it has pleochroism. When a mineral is anisotropic, one can see whether it is uniaxial or biaxial, depending on how fast the rays of light are moving through the mineral. This mineral is uniaxial negative due to the ordinary ray being slower than the extraordinary ray. Occurrence Metazeunerite is an uncommon radioactive secondary mineral found in "arsenic bearing hydrothermal uraniu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Sunglasses
Sunglasses or sun glasses (informally called shades or sunnies; more names below) are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. In the early 20th century, they were also known as sun cheaters (cheaters then being an American slang term for glasses). Since the 1930s, sunglasses have been a popular fashion accessory, especially on the beach. The American Optometric Association recommends wearing sunglasses that block ultraviolet radiation (UV) whenever a person is in the sunlight to protect the eyes from UV and blue light, which can cause several serious eye problems. Their usage is mandatory immediately after some surgical procedures, such as LASIK, and recommended for a certain time period in dusty areas, when leaving ...

Jewelry
Jewellery ( UK) or jewelry (U.S.) consists of decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks. Jewellery may be attached to the body or the clothes. From a western perspective, the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal such as gold often combined with gemstones, has been the normal material for jewellery, but other materials such as glass, shells and other plant materials may be used. Jewellery is one of the oldest types of archaeological artefact – with 100,000-year-old beads made from ''Nassarius'' shells thought to be the oldest known jewellery.Study reveals 'oldest jewellery' , '' |
Gemstone
A gemstone (also called a fine gem, jewel, precious stone, or semiprecious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks (such as lapis lazuli, opal, and obsidian) and occasionally organic materials that are not minerals (such as amber, jet, and pearl) are also used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity and notoriety are other characteristics that lend value to gemstones. Apart from jewelry, from earliest antiquity engraved gems and hardstone carvings, such as cups, were major luxury art forms. A gem expert is a gemologist, a gem maker is called a lapidarist or gemcutter; a diamond cutter is called a diamantaire.

Braemar Castle
Braemar Castle is situated near the village of Braemar in Aberdeenshire, Scotland. It is a possession of the chief of Clan Farquharson and is leased to a local charitable foundation. It is open to the public. History From the Late Middle Ages, the castle was a stronghold of the Earls of Mar. The present Braemar Castle was constructed in 1628 by John Erskine, Earl of Mar, as a hunting lodge and to counter the rising power of the Farquharsons,''Braemar Castle'', Nevisprint Ltd, Fort William, 20 pages, replacing an older building, which was the successor of nearby Kindrochit Castle, which dates from the 11th century AD. The siting of Kindrochit Castle was based upon the strategic location of this site relative to historic crossings of the Grampian Mounth. An important garrison after the 1745 Jacobite rising, Braemar Castle had been attacked and burned by John Farquharson, the ''Black Colonel'' of Inverey during the Jacobite rising of 1689, to prevent it being used as a ga ...

Sgian-dubh
The ( ; ) – also anglicized as skene – is a small, single-edged knife ( gd, sgian) worn as part of traditional Scottish Highland dress along with the kilt. Originally used for eating and preparing fruit, meat, and cutting bread and cheese, as well as serving for other more general day-to-day uses such as cutting material and protection, it is now worn as part of traditional Scottish dress tucked into the top of the kilt hose with only the upper portion of the hilt visible. The is normally worn on the same side as the dominant hand. Etymology and spelling The name comes from the Scottish Gaelic '. Although the primary meaning of ' is "black", the secondary meaning of "hidden" is at the root of ', based on the stories and theories surrounding the knife's origin, in particular those associated with the Highland custom of depositing weapons at the entrance to a house prior to entering as a guest.

Anglicised
Anglicisation is the process by which a place or person becomes influenced by English culture or British culture, or a process of cultural and/or linguistic change in which something non-English becomes English. It can also refer to the influence of English culture and business on other countries outside England or the United Kingdom, including their media, cuisine, popular culture, technology, business practices, laws, or political systems. Linguistic anglicisation is the practice of modifying foreign words, names, and phrases to make them easier to spell, pronounce or understand in English. The term commonly refers to the respelling of foreign words, often to a more drastic degree than that implied in, for example, romanisation. One instance is the word "dandelion", modified from the French ''dent-de-lion'' ("lion's tooth", a reference to the plant's sharply indented leaves). The term can also refer to phonological adaptation without spelling change: ''spaghetti'', for example ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilt
A kilt ( gd, fèileadh ; Irish: ''féileadh'') is a garment resembling a wrap-around knee-length skirt, made of twill woven worsted wool with heavy pleats at the sides and back and traditionally a tartan pattern. Originating in the Scottish Highland dress for men, it is first recorded in 16th century as the great kilt, a full-length garment whose upper half could be worn as a cloak. The small kilt or ''modern kilt'' emerged in the 18th century, and is essentially the bottom half of the great kilt. Since the 19th century, it has become associated with the wider culture of Scotland, and more broadly with Gaelic or Celtic heritage. Although the kilt is most often worn by men on formal occasions and at Highland games and other sports events, it has also been adapted as an item of informal male clothing, returning to its roots as an everyday garment. Kilts are now made for casual wear in a variety of materials. Alternative fastenings may be used and pockets inserted to avoid the ...
