Jewelry Television is an American television network specializing in the sale of jewelry for both men and women. On-air and online, the network is mainly branded by its jtv initials in lower-case letters. It has an estimated reach of more than 80 million U.S. households, through cable and satellite providers, online streaming and limited over-the-air broadcasters. The headquarters of Jewelry Television are located in Knoxville, Tennessee. It has manufacturing facilities in Sri Lanka, Hong Kong, and Thailand. History Jewelry Television was founded as America's Collectibles Network (ACN) in 1993 by Jerry Sisk Jr., Bob Hall, and Bill Kouns. Sisk was a graduate gemologist, Kouns was a jewelry expert, and Hall had previously worked in the television industry. The fledgling network began broadcasting from a studio in Greeneville, Tennessee, with just one television camera. ACN initially sold gemstones, jewelry, and collectible coins. Sisk, Hall, and Kouns later moved the network ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1080i
1080i (also known as Full HD or BT.709) is a combination of frame resolution and scan type. 1080i is used in high-definition television (HDTV) and high-definition video. The number "1080" refers to the number of horizontal lines on the screen. The "i" is an abbreviation for "interlaced"; this indicates that only the even lines, then the odd lines of each frame (each image called a video field) are drawn alternately, so that only half the number of actual image frames are used to produce video. A related display resolution is 1080p, which also has 1080 lines of resolution; the "p" refers to progressive scan, which indicates that the lines of resolution for each frame are "drawn" on the screen in sequence. The term assumes a widescreen aspect ratio of 16:9 (a rectangular TV that is wider than it is tall), so the 1080 lines of vertical resolution implies 1920 columns of horizontal resolution, or 1920 pixels × 1080 lines. A 1920 pixels × 1080 lines screen has a total of 2.1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greeneville, Tennessee
Greeneville is a town in and the county seat of Greene County, Tennessee, United States. The population as of the 2020 census was 15,479. The town was named in honor of Revolutionary War hero Nathanael Greene, and it is the second oldest town in Tennessee. It is the only town with this spelling in the United States, although there are numerous U.S. towns named ''Greenville''. The town was the capital of the short-lived State of Franklin in the 18th-century history of East Tennessee. Greeneville is known as the town where United States President Andrew Johnson began his political career when elected from his trade as a tailor. He and his family lived there for most of his adult years. It was an area of strong abolitionist and Unionist views and yeoman farmers, an environment that influenced Johnson's outlook. The Greeneville Historic District was established in 1974. The U.S. Navy was named in honor of the town. Greeneville is part of the Johnson City- Kingsport- Bristol ...

Montgomery, Alabama
Montgomery is the capital city of the U.S. state of Alabama and the county seat of Montgomery County. Named for the Irish soldier Richard Montgomery, it stands beside the Alabama River, on the coastal Plain of the Gulf of Mexico. In the 2020 census, Montgomery's population was 200,603. It is the second most populous city in Alabama, after Huntsville, and is the 119th most populous in the United States.

In February 1861, Montgomery was chosen the first capital of the Confederate States of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Characteristics and classification The traditional classification in the West, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labradorite
Labradorite (( Ca, Na)( Al, Si)4 O8) is a calcium-enriched feldspar mineral first identified in Labrador, Canada, which can display an iridescent effect ( schiller). Labradorite is an intermediate to calcic member of the plagioclase series. It has an anorthite percentage (%An) of between 50 and 70. The specific gravity ranges from 2.68 to 2.72. The streak is white, like most silicates. The refractive index ranges from 1.559 to 1.573 and twinning is common. As with all plagioclase members, the crystal system is triclinic, and three directions of cleavage are present, two of which are nearly at right angles and are more obvious, being of good to perfect quality (while the third direction is poor). It occurs as clear, white to gray, blocky to lath shaped grains in common mafic igneous rocks such as basalt and gabbro, as well as in anorthosites. Occurrence The geological type area for labradorite is Paul's Island near the town of Nain in Labrador, Canada. It has also been r ...

Andesine
Andesine is a silicate mineral, a member of the plagioclase feldspar solid solution series. Its chemical formula is ( Ca, Na)( Al, Si)4 O8, where Ca/(Ca + Na) (% anorthite) is between 30–50%. The formula may be written as Na0.7-0.5Ca0.3-0.5Al1.3-1.5Si2.7-2.5O8. The plagioclase feldspars are a continuous solid solution series and as such the accurate identification of individual members requires detailed optical study, chemical analysis or density measurements. Refractive indices and specific gravity increase directly with calcium content.Klein, Cornelis, and Cornelius S. Hurlbut, Jr., ''Manual of Mineralogy,'' Wiley, 20th ed. 1985, p. 455 It is sometimes used as a gemstone. Name and discovery Andesine was first described in 1841 for an occurrence in the Marmato mine, Marmato, Cauca, Chocó Department, Colombia. The name is for the Andes due to its abundance in the andesite lavas in those mountains. In the early 2000s, red and green gemstones began to be marketed under the ...

Lloyd's Of London
Lloyd's of London, generally known simply as Lloyd's, is an insurance and reinsurance market located in London, England. Unlike most of its competitors in the industry, it is not an insurance company; rather, Lloyd's is a corporate body governed by the Lloyd's Act 1871 and subsequent Acts of Parliament. It operates as a partially-mutualised marketplace within which multiple financial backers, grouped in syndicates, come together to pool and spread risk. These underwriters, or "members", are a collection of both corporations and private individuals, the latter being traditionally known as "Names". The business underwritten at Lloyd's is predominantly general insurance and reinsurance, although a small number of syndicates write term life insurance. The market has its roots in marine insurance and was founded by Edward Lloyd at his coffee house on Tower Street in 1688. Today, it has a dedicated building on Lime Street which is Grade I listed. Traditionally business is tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-definition Television
High-definition television (HD or HDTV) describes a television system which provides a substantially higher image resolution than the previous generation of technologies. The term has been used since 1936; in more recent times, it refers to the generation following standard-definition television (SDTV), often abbreviated to HDTV or HD-TV. It is the current de facto standard video format used in most broadcasts: terrestrial broadcast television, cable television, satellite television and Blu-ray Discs. Formats HDTV may be transmitted in various formats: * 720p (1280 horizontal pixels × 720 lines): 921,600 pixels * 1080i (1920×1080) interlaced scan: 1,036,800 pixels (~1.04 MP). * 1080p (1920×1080) progressive scan: 2,073,600 pixels (~2.07 MP). ** Some countries also use a non-standard CEA resolution, such as 1440×1080i: 777,600 pixels (~0.78 MP) per field or 1,555,200 pixels (~1.56 MP) per frame When transmitted at two megapixels per frame, HDTV provides about five times ...

Grey Market
A grey market or dark market (sometimes confused with the similar term " parallel market") is the trade of a commodity through distribution channels that are not authorized by the original manufacturer or trade mark proprietor. Grey market products (grey goods) are products traded outside the authorized manufacturer's channel. Etymology Manufacturers of computers, telecom, and technology equipment often sell these products through distributors. Most distribution agreements require the distributor to resell the products strictly to end users. However, some distributors choose to resell products to other resellers. In the late 1980s, manufacturers labelled the resold products as the "grey market". The legality of selling "grey market" products depends on a number of factors. Courts in the United States and in the EU make a number of assessments, including an examination of the physical and non-physical differences between the "grey market" and authorized products to determin ...
