Jewelry is a form of personal adornment, manifesting itself as necklaces, rings, brooches, earrings and bracelets. Jewelry made from any material, usually gemstones, precious metals or shells. Factors affecting the choice of materials include cultural differences and the availability of the materials. Jewelry appreciated because of its material properties, its patterns or for meaningful symbols. Jewelry differs from other items of personal adornment in that it has no other purpose than to look appealing. Items such as belts and handbags are accessories rather than jewelry. Jewelry regarded as a way of storing wealth and might possess some minimal functionality, such as holding a garment together or keeping hair in place. It has from very early times regarded as a form of personal adornment. The first pieces of jewelry made from natural materials, such as bone, animal teeth, shell, wood and carved stone. Some jewelry throughout the ages may have specifically been as an indication of a social group. Exotic jewelry is often for wealthier people, with its rarity increasing its value. Due to its personal nature and its indication of social class, some cultures established traditions of burying the dead with their jewelry. Jewelry made to adorn nearly every body part, from hairpins to toe rings and many more types of jewelry. While high-quality jewelry made with gemstones and precious metals, such as silver or gold, there is also a growing demand for art jewelry where design and creativity prized above material value. In addition, there is the less costly costume jewelry, made from lower value materials and mass-produced. Other variations include wire sculpture jewelry, using anything from base metal wire with rock tumbled stone to precious metals and precious gemstones. In creating jewelry, gemstones, coins, or other precious items are often used, and they are typically set into precious metals. Alloys of nearly every metal encountered in jewelry - bronze, for example, was common in Roman times. Modern fine jewelry usually includes gold, white gold, platinum, palladium, titanium or silver. Most American and European gold jewelry is made of an alloy of gold, the purity stated in karats, indicated by a number followed by the letter K. American gold jewelry must be of at least 10K purity. Many precious and semiprecious stones used for jewelry. For platinum, gold, and silver jewelry, there are many techniques to create finishes. The most common are high-polish, satin/matte, brushed, and hammered. High-polished jewelry is by far the most common and gives the metal the highly reflective and shiny look. Satin or matte finish reduces the shine and reflection of the jewelry and commonly used to accentuate gemstones such as diamonds. Brushed finishes give the jewelry a textured look, and are created by brushing a material (similar to sandpaper) against the metal, leaving 'brush strokes'. Hammered finishes typically created by using a soft, rounded hammer and hammering the jewelry to give it a wavy texture. Some jewelry plated to give it a shiny, reflective look or to achieve a desired color. Sterling silver jewelry may plate with a thin layer of 0.999 fine silver or plated with rhodium or gold. Base metal costume jewelry plated with silver, gold, or rhodium for a more attractive finish. The modern jewelry movement began in the late 1940s with a renewed interest in artistic and leisurely pursuits. The advent of new materials, such as plastics, Precious Metal Clay and coloring techniques, has led to increased variety in styles. Other advances, such as the development of improved pearl harvesting by people such as and the development of improved quality artificial gemstones such as moissanite has placed jewelry within the economic grasp of a much larger segment of the population. Influence from other cultural forms is also evident; one example of this is bling-bling style jewelry, popularized by hip-hop and rap artists in the early 21st century. The late 20th century saw the blending of European design with oriental techniques. The following are innovations in the decades straddling the year 2000: Hydraulic die forming, anti-classic raising, fold forming, reactive metal anodizing, shell forms, PMC, photo etching, and CAD/CAM. Artisan jewelry continues to grow as both a hobby and a profession. With more than 17 United States periodicals about beading alone, resources, accessibility and a low initial cost of entry continues to expand production of hand-made adornments.

Rings

A finger ring is a circular band worn as a type of ornamental jewelry around a finger; it is the most common current meaning of the word ring. Other types of metal bands worn as ornaments called rings, such as arm rings and neck rings. Rings worn by both men and women and can be of any quality. Various ring shapes and styles exist. The following are but a few. Flat wedding bands are the simplest form of ring. A flat wedding band consists of a strip of metal bent around into a loop and joined where the ends meet. Half-round rings, also called D-shape rings, are flat wedding bands filed half-round on the outside. Sleeve rings are rings that consist of a thin inner ring or sleeve, with several other rings stacked onto it to form one solid ring. Either the rings soldered onto the sleeve or the ends of the sleeve can be upset to keep them all together. A little of both can also be done. Solitaire rings are rings with a single large stone as a centerpiece, usually a diamond. Eternity rings are rings with stones, usually diamonds, of the same cut and size, set in one row all around the ring. The stones are usually round or square, and the setting is usually either claws or a channel setting. When the stones do not continue around the entire ring, but stop halfway around the finger, it is a half-eternity ring. Trinity rings or Trilogy Rings are three rings worn at one time. Cluster rings are rings with a group of stones in a cluster setting, forming the focal point of the ring. The cluster setting usually consists of one large stone in the center surrounded with several smaller stones. Tension Rings are a type of ring in which a single gemstone is held in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone. In the United States and Canada, ring sizes specified using a numerical scale, with quarter and half sizes. An increase of a full size is an increase of 0.032 inch in diameter, or roughly 1/10 inch in inside circumference. Generally, sizes in quarters and halves will not relate conventionally to anything on any known ruler. On one finger alone, a person may vary more than a whole ring size- depending on time of day, work performed, and other swelling-inducing activities/conditions. Therefore, in most cases quarter-sizes are meaningless unless one needs precise accuracy with a particular ring.
