Jeweller
A bench jeweler is an artisan who uses a combination of skills to make and repair jewelry. Some of the more common skills that a bench jeweler might employ include antique restoration, silversmithing, goldsmithing, stone setting, engraving, fabrication, wax carving, lost-wax casting, electroplating, forging, & polishing. Jewelry manufacture In general, an original design is made and sold using processes such as molding, casting, stamping and similar techniques. The other is original, one of a kind work. The bench jeweler will be a factor in many facets of the process, depending on what is needed and the skills of the worker. When a production piece is contemplated, it may go through a design process that can range from one person with an idea to a full-scale planning stage involving teams of artists and marketing professionals. Eventually, that design will need to be made into a real piece of metal jewelry, which is generally called a model, and the worker who makes it is ...

Jewellery
Jewellery (or jewelry in American English) consists of decorative items worn for personal adornment such as brooches, ring (jewellery), 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 Ornament (art), 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. The basic forms of jewellery vary between cultures but are often extremely long-lived; in European cultures the most common forms of jewellery listed above have persisted since ancient times, while other forms such as adornments for the nose or ankle, impo ...

Gemstone
A gemstone (also called a fine gem, jewel, precious stone, semiprecious stone, or simply gem) is a piece of mineral crystal which, when cut or polished, is used to make jewellery, jewelry or other adornments. Certain Rock (geology), rocks (such as lapis lazuli, opal, and obsidian) and occasionally organic chemistry, organic materials that are not minerals (such as amber, Jet (gemstone), jet, and pearl) may also be used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some softer minerals such as brazilianite may be used in jewelry because of their color or Lustre (mineralogy), luster or other physical properties that have aesthetic value. However, generally speaking, soft minerals are not typically used as gemstones by virtue of their brittleness and lack of durability. Found all over the world, the industry of coloured gemstones (i.e. anything other than diamonds) is currently estimated at US$1.55billion and is projected to s ...

Engraving
Engraving is the practice of incising a design on a hard, usually flat surface by cutting grooves into it with a Burin (engraving), burin. The result may be a decorated object in itself, as when silver, gold, steel, or Glass engraving, glass are engraved, or may provide an Intaglio (printmaking), intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engravings, a form of relief printing and stone engravings, such as petroglyphs, are not covered in this article. Engraving was a historically important method of producing images on paper in artistic printmaking, in mapmaking, and also for commercial reproductions and illustrations for books and magazines. It has long been replaced by various photographic processes in its commercial applications and, partly because of the difficulty of learning the techni ...

Goldsmith
A goldsmith is a Metalworking, metalworker who specializes in working with gold and other precious metals. Modern goldsmiths mainly specialize in jewelry-making but historically, they have also made cutlery, silverware, platter (dishware), platters, goblets, decorative and serviceable utensils, and ceremonial or religious items. Goldsmiths must be skilled in forming metal through file (tool), filing, brazing, soldering, sawing, forging, Casting (metalworking), casting, and polishing. The trade has very often included jewelry-making skills, as well as the very similar skills of the silversmith. Traditionally, these skills had been passed along through apprenticeships; more recently jewelry arts schools, specializing in teaching goldsmithing and a multitude of skills falling under the jewelry arts umbrella, are available. Many universities and junior colleges also offer goldsmithing, silversmithing, and metal arts fabrication as a part of their fine arts curriculum. Gold Compar ...

Lost-wax Casting
Lost-wax castingalso called investment casting, precision casting, or ''cire perdue'' (; borrowed from French)is the process by which a duplicate sculpture (often a metal, such as silver, gold, brass, or bronze) is cast from an original sculpture. Intricate works can be achieved by this method. The oldest known examples of this technique are approximately 6,500 years old (4550–4450 BC) and attributed to gold artefacts found at Bulgaria's Varna Necropolis. A copper amulet from Mehrgarh, Indus Valley civilization, in present-day Pakistan, is dated to circa 4,000 BC. Cast copper objects, found in the Nahal Mishmar hoard in southern Israel, which belong to the Chalcolithic period (4500–3500 BC), are estimated, from carbon-14 dating, to date to circa 3500 BC. Other examples from somewhat later periods are from Mesopotamia in the third millennium BC. Lost-wax casting was widespread in Europe until the 18th century, when a piece-moulding process came to predominate. The step ...

Stonesetting
Stonesetting is the art of securely setting or attaching gemstones into jewelry. Cuts There are two general types of gemstone cutting: cabochon and facet. Cabochons are smooth, often domed, with flat backs. Agates and turquoise are usually cut this way, but precious stones such as rubies, emeralds and sapphires may also be. Many stones like star sapphires and moonstones must be cut this way in order to properly display their unusual appearance. A faceted shape resembles that of the modern diamond Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Diamond is tasteless, odourless, strong, brittle solid, colourless in pure form, a poor conductor of e .... It has a flat, polished surface, typically with a transparent surface that refracts light inside the gemstone and reflects light on the outside. In the case of a cabochon stone, the side of the stone is usually cut at a shallow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silversmith
A silversmith is a metalworker who crafts objects from silver. The terms ''silversmith'' and ''goldsmith'' are not exact synonyms, as the techniques, training, history, and guilds are (or were, at least) largely the same but differed in that the end product may vary greatly (as may the scale of objects created). History In the ancient Near East (as holds true today), the value of silver was lower than the value of gold, allowing a silversmith to produce objects and store them as stock. Historian Jack Ogden states that, according to an edict written by Diocletian in 301 A.D., a silversmith was able to charge 75, 100, 150, 200, 250, or 300 '' denarii'' per Roman pound for material produce. At that time, guilds of silversmiths formed to arbitrate disputes, protect its members' welfare, and educate the public of the trade. Silversmiths in medieval Europe and England formed guilds and transmitted their tools and techniques to new generations via the apprentice tradition. Silverwo ...

Brazing
Brazing is a metal-joining process in which two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal. Brazing differs from welding in that it does not involve melting the work pieces. Brazing differs from soldering through the use of a higher temperature and much more closely fitted parts. During the brazing process, the filler metal flows into the gap between close-fitting parts by capillary action. The filler metal is brought slightly above its melting ( liquidus) temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal (in a process known as wetting) and is then cooled to join the work pieces together. Brazing joins the same or different metals with considerable strength. Process Brazing has many advantages over other metal-joining techniques, such as welding. Since brazing does not melt the base metal of the joi ...

Forging
Forging is a manufacturing process involving the shaping of metal using localized compression (physics), compressive forces. The blows are delivered with a hammer (often a power hammer) or a die (manufacturing), die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Degarmo, p. 389 Forging has been done by metalsmith, smiths for millennia; the traditional products were kitchenware, household hardware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanism (engineering), mechanisms and machines wherever a component requires high strength of materials, strength; such forgings usually require further processing (such as machining) ...

Seybold Building
Seybold Building is a historic jewelry building in Miami, Florida. It was designed by Kiehnel and Elliott. The building was erected in two stages. The first three levels of the building were completed in 1921. John Seybold had a bakery and confectionery business which he operated on the main floor. An additional seven stories were added above the annex in 1925. The Seybold Building is a City of Miami historic landmark. Seybold sold the complex in 1941. It is a National Register of Historic Places contributing property as part of the Downtown Miami Historic District. History The Seybold building was built back in 1926 as the brainchild of its namesake, John Seybold, who moved to Miami in the late 19th century and eventually set up a bakery. That business burned down, but he bounced back with another bakery. He then went on to run a shopping mall, called an arcade back then, that became the basis of the 10-story Seybold building, which is the second largest diamond and jewelry c ...

Cuban Revolution
The Cuban Revolution () was the military and political movement that overthrew the dictatorship of Fulgencio Batista, who had ruled Cuba from 1952 to 1959. The revolution began after the 1952 Cuban coup d'état, in which Batista overthrew the emerging Cuban democracy and consolidated power. Among those who opposed the coup was Fidel Castro, then a young lawyer, who initially tried to challenge the takeover through legal means in the Cuban courts. When these efforts failed, Fidel Castro and his brother Raúl Castro, Raúl led an armed Attack on the Moncada Barracks, assault on the Moncada Barracks, a Cuban military post, on 26 July 1953. Following the attack's failure, Fidel Castro and his co-conspirators were arrested and formed the 26th of July Movement (M-26-7) in detention. At his trial, Fidel Castro launched into a History Will Absolve Me, two-hour speech that won him national fame as he laid out his grievances against the Batista dictatorship.
