Bezel (jewellery)
A bezel is a wider and usually thicker section of the hoop of a Ring (jewellery), ring, which may contain a gemstone, gem or a flat surface (usually with an engraved design, as in a signet ring). Rings are normally worn to display bezels on the upper or outer side of the finger. In gem-cutting the term ''bezel'' is used for those sloping facets (also called sides or faces) of a cut stone that surround the flat ''table'' face,OED, "Bezel" noun, 1 and 2; "In lapidary usage, the oblique sides or faces of a cut gem", Campbell. which is the large, horizontal facet on the top. More broadly, bezels are found on tools and appliances. The sloping face of a chisel is known as a bezel. In vehicles, it is the part of the bodywork that surrounds a headlight or turn signal. On a cell phone or tablet, it is the back surface that frames the LCD screen. The word may also refer to a bezel setting for a stone, which is a general term for a Stonesetting, setting holding the stone in place with a ...

Bevel
A bevelled edge (UK) or beveled edge (US) is an edge of a structure that is not perpendicular to the faces of the piece. The words bevel and chamfer overlap in usage; in general usage, they are often interchanged, while in technical usage, they may be differentiated as shown in the image on the right. A bevel is typically used to soften the edge of a piece for the sake of safety, wear resistance, aesthetics; or to facilitate engineering fit, mating with another piece. Applications Cutting tools Most cutting tools have a bevelled edge which is apparent when one examines the grind. Bevel angles can be duplicated using a sliding T bevel. Graphic design Typographic bevels are shading and artificial shadows that emulate the appearance of a three-dimensional space, 3-dimensional letter. The bevel is a relatively common effect in graphic editors such as Adobe Photoshop, Photoshop. As such, it is in widespread use in mainstream logos and other design elements.

Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the principal historical dictionary of the English language, published by Oxford University Press (OUP), a University of Oxford publishing house. The dictionary, which published its first edition in 1884, traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, and provides ongoing descriptions of English language usage in its variations around the world. In 1857, work first began on the dictionary, though the first edition was not published until 1884. It began to be published in unbound Serial (literature), fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 b ...

Turning The Bezel On A Diving Watch To Mark A Point In Time
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates. Usually the term "turning" is reserved for the generation of ''external'' surfaces by this cutting action, whereas this same essential cutting action when applied to ''internal'' surfaces (holes, of one kind or another) is called " boring". Thus the phrase "turning and boring" categorizes the larger family of processes known as lathing. The cutting of faces on the workpiece, whether with a turning or boring tool, is called "facing", and may be lumped into either category as a subset. Turning can be done manually, in a traditional form of lathe, which frequently requires continuous supervision by the operator, or by using an automated lathe which does not. Today the most common type of such automation is computer numerical control, better known as CNC. (CNC is also commonly used with many other types ...

Prong Setting
Prong setting or prong mount refers to the use of metal projections or tines, called " prongs", to secure a gemstone to a piece of jewelry. A prong setting is one component of what is known to jewelers as a ''head'', a claw-shaped type of binding (typically three, four, or six individual prongs per head) that is welded or soldered to a jewelry item to mount (or "set") a gemstone to the jewelry item. A common setting for diamond engagement rings, the prong setting allows light to strike a gemstone from more angles, increasing its brilliance. Prong-setting engagement rings are sometimes referred to as Tiffany setting rings, although this is a trademarked term specifically used to describe prong setting rings sold by Tiffany & Co. A 2017, $19 million lawsuit confirmed the exclusive right of Tiffany & Co. to use the term "Tiffany" within the jewelry sales industry. The judgment was eventually overturned, and the parties made a confidential settlement. Characteristics General feat ... [...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. The earliest diamond cutting techniques were simply to polish the natural shape of rough diamonds, often octahedral crystals. It wasn't until the 14th century that faceting, the process of cutting and polishing a gemstone to create multiple flat surfaces or facets, was first developed in Europe. 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 ...

Angle
In Euclidean geometry, an angle can refer to a number of concepts relating to the intersection of two straight Line (geometry), lines at a Point (geometry), point. Formally, an angle is a figure lying in a Euclidean plane, plane formed by two Ray (geometry), rays, called the ''Side (plane geometry), sides'' of the angle, sharing a common endpoint, called the ''vertex (geometry), vertex'' of the angle. More generally angles are also formed wherever two lines, rays or line segments come together, such as at the corners of triangles and other polygons. An angle can be considered as the region of the plane bounded by the sides. Angles can also be formed by the intersection of two planes or by two intersecting curves, in which case the rays lying tangent to each curve at the point of intersection define the angle. The term ''angle'' is also used for the size, magnitude (mathematics), magnitude or Physical quantity, quantity of these types of geometric figures and in this context an a ...

Cabochon
A cabochon (; ) is a gemstone that has been shaped and polished, as opposed to faceted. The resulting form is usually a convex (rounded) obverse with a flat reverse. Cabochon was the default method of preparing gemstones before gemstone cutting developed. Application Cutting ''en cabochon'' (French: "in the manner of a cabochon") is usually applied to opaque gems, while faceting is usually used for transparent stones. Hardness is also taken into account as softer gemstones with a hardness lower than 7 on the Mohs hardness scale are easily scratched, mainly by silicon dioxide in dust and grit. This would quickly make translucent gems unattractive—instead they are polished as cabochons, making the scratches less evident. In asteriated stones such as star sapphires and chatoyant stones such as cat's eye chrysoberyl, a domed cabochon cut can show the star or eye, which would not be visible in a faceted cut. The usual shape for cutting cabochons is an ellipse, because the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soldered
Solder (; NA: ) is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling. Metals or alloys suitable for use as solder should have a lower melting point than the pieces to be joined. The solder should also be resistant to oxidative and corrosive effects that would degrade the joint over time. Solder used in making electrical connections also needs to have favorable electrical characteristics. Soft solder typically has a melting point range of , and is commonly used in electronics, plumbing, and sheet metal work. Alloys that melt between are the most commonly used. Soldering performed using alloys with a melting point above is called "hard soldering", "silver soldering", or brazing. In specific proportions, some alloys are eutectic — that is, the alloy's melting point is the lowest possible for a mixture of those components, and coi ...

Diamond Bezel Set From Jens Hansen
Diamond is a 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 electricity, and insoluble in water. 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. 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) can color a diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, oran ...

Chamfer
A chamfer ( ) is a transitional edge between two faces of an object. Sometimes defined as a form of bevel, it is often created at a 45° angle between two adjoining right-angled faces. Chamfers are frequently used in machining, carpentry, furniture, concrete formwork, mirrors, and to facilitate assembly of many mechanical engineering designs. Terminology In materials and manufacturing, a ''chamfer'' is used to "ease" otherwise sharp edges, both for safety and to prevent damage to the edges; it may also be a primarily decorative feature. In general terms it may be regarded as a type of ''bevel'', and the terms are often used interchangeably. However, in machining, only the term chamfer is used for the specific technique, practice, and result. In carpentry, a lark's tongue is a chamfer which ends short of the end of a piece in a gradual outward curve, leaving the remainder of the edge as a right angle. Chamfers may be formed in either inside or outside adjoining faces of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
