Gold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native) form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium and also as mineral inclusions such as within pyrite.
Jewelry or jewelry consists of decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks. Jewelry may be attached to the body or the clothes. From a western perspective, the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal such as gold used in different carats from 21, 18, 12, 9 or even lower, often combined with gemstones, has been the normal material for jewelry, but other materials such as shells and other plant materials may be used. It is one of the oldest type of archaeological artefact – with 100,000-year-old beads made from Nassarius shells thought to be the oldest known jewelry. The basic forms of jewelry vary between cultures but are often extremely long-lived; in European cultures the most common forms of jewelry listed above have persisted since ancient times, while other forms such as adornments for the nose or ankle, important in other cultures, are much less common.
Jewelry may be made from a wide range of materials. Gemstones and similar materials such as amber and coral, precious metals, beads, and shells have been widely used, and enamel has often been important. In most cultures’ jewelry can be understood as a status symbol, for its material properties, its patterns, or for meaningful symbols. Jewelry has been made to adorn nearly every body part, from hairpins to toe rings, and even genital jewelry.
