Asscher Cut
The Royal Asscher Diamond Company ( nl, Koninklijke Asscher Diamant Maatschappij) was founded in 1854 by the Asscher family of gemcutters. The company is responsible for cutting some of the most famous diamonds in the world including two of the top three largest diamonds ever found. Its headquarters still stand at its original location Tolstraat 127 in Amsterdam, the Netherlands. The company also has regional headquarters in New York City (Royal Asscher of America) and Tokyo (Royal Asscher of Japan). Royal Asscher is still owned by the Asscher family, today a renowned diamond dynasty. The Asscher Diamond Company, made famous at the turn of the 20th century by Joseph and Abraham Asscher, became Royal Asscher Diamond Company in 1980 when it was bestowed with the Dutch Royal Predicate from Queen Juliana of the Netherlands in recognition of the company's stature both in the Netherlands and across the world. In 2011 Queen Beatrix perpetuated the Royal Prefix for another 25 years. Hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond Cuttery Asscher
Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the chemically stable form of carbon at room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange, or red. Diamond also has a very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facet
Facets () are flat faces on geometric shapes. The organization of naturally occurring facets was key to early developments in crystallography, since they reflect the underlying symmetry of the crystal structure. Gemstones commonly have facets cut into them in order to improve their appearance by allowing them to reflect light. Facet arrangements Of the hundreds of facet arrangements that have been used, the most famous is probably the round brilliant cut, used for diamond and many colored gemstones. This first early version of what would become the modern Brilliant Cut is said to have been devised by an Italian named Peruzzi, sometime in the late 17th century.Gems, 5th edition, Webster, 1995.Gemstones of the world, Schumann, 1977. Later on, the first angles for an "ideal" cut diamond were calculated by Marcel Tolkowsky in 1919. Slight modifications have been made since then, but angles for "ideal" cut diamonds are still similar to Tolkowsky's formula. Round brilliants cut b ...

Manufacturing Companies Based In Amsterdam
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end user In product development, an end user (sometimes end-user) is a person who ultimately uses or is intended to ultimately use a product. The end user stands in contrast to users who support or maintain the product, such as sysops, system administrat ...s and consumers (usually through wholesalers, who in t ...

Buildings And Structures In Amsterdam
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artisti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Koninklijk
or (, Dutch for 'royal') is an honorary title given to certain companies and non-profit organisations in the Netherlands and to a lesser extent Belgium, by the monarchs of each country. It was first introduced by Louis Bonaparte in 1807, then King of Holland, who awarded the title to cultural associations. Companies awarded with the title may opt to use the English equivalent ''royal'' instead. It is comparable with the Royal Warrant in the United Kingdom. The word is also used in the names of some state-controlled organisations, such as the . In the Netherlands The monarch of the Netherlands has the right to appoint the royal title to a company or organisation. To qualify for a nomination, the company or organization has to meet the following conditions: * it has to be leading in its field of expertise; * it has to have national importance; * it has to be in existence for at least 100 years (in principle).
