A necklace is an article of jewellery that is worn around the neck. Necklaces may have been one of the earliest types of adornment worn by humans. They often serve ceremonial, religious, magical, or funerary purposes and are also used as symbols of wealth and status, given that they are commonly made of precious metals and stones.

The main component of a necklace is the band, chain, or cord that wraps around the neck. These are most often rendered in precious metals such as gold, silver, and platinum. Necklaces often have additional attachments suspended or inset into the necklace itself. These attachments typically include pendants, lockets, amulets, crosses, and precious and semi-precious materials such as diamond, pearls, rubies, emeralds, garnets, and sapphires. They are made with many different type of materials and are used for many things and sometimes classed as clothing.

Historical Necklaces

Prehistoric neckware 
Prehistoric peoples often used natural materials such as feathers, bone, shells, and plant materials to create necklaces. Evidence of early Upper Paleolithic necklace making in southern Africa and east Africa dates back to 50,000 BP. By the Bronze Age metallic jewellery had replaced pre-metallic adornments. Necklaces were first depicted in statuary and art of the Ancient Near East, and early necklaces made of precious metals with inset stones were created in Europe.

Ancient civilizations 

In Ancient Mesopotamia, cylinder seals were often strung and worn as jewellery. In Ancient Babylon, necklaces were made of carnelian, lapis lazuli, agate, and gold, which was also made into gold chains. Ancient Sumerians created necklaces and beads from gold, silver, lapis lazuli and carnelian. In Ancient Egypt, a number of difference necklace types were worn. Upper-class Ancient Egyptians wore collars of organic or semi-precious and precious materials for religious, celebratory, and funerary purposes. These collars were often ornamented with semi-precious, glass, pottery, and hollow beads. Beads made from a variety of precious and semi-precious materials were also commonly strung together to create necklaces. Gold that was fashioned into stylised plant, animal, and insect shapes were common as well. Amulets were also turned into necklaces.  In Ancient Crete necklaces were worn by all classes; peasants wore stones on flax thread while the wealthy wore beads of agate, pearl, carnelian, amethyst, and rock crystal. Pendants shaped into birds, animals, and humans were also worn, in addition to paste beads.
 In Ancient Greece, delicately made gold necklaces created with repoussé and plaited gold wires were worn. Most often these necklaces were ornamented with blue or green enameled rosettes, animal shapes, or vase-shaped pendants that were often detailed with fringes. It was also common to wear long gold chains with suspended cameos and small containers of perfume. New elements were introduced in the Hellenistic period; colored stones allowed for poly-chromatic pieces, and animal-head finials and spear-like or bud shaped pendants were hung from chains. Ancient Etruscans used granulation to create granulated gold beads which were strung with glass and faience beads to create colorful necklaces. In Ancient Rome necklaces were among the many types of jewellery worn by the Roman elite. Gold and silver necklaces were often ornamented with foreign and semi-precious objects such as amber, pearl, amethyst, sapphire, and diamond. In addition, ropes of pearls, gold plates inset with enamel, and lustrous stones set in gold filigree were often worn. Many large necklaces and the materials that adorned the necklaces were imported from the Near East.   
 Later in the empire, following barbarian invasions, colorful and gaudy jewellery became popular. In the Byzantine era, ropes of pearls and embossed gold chains were most often worn, but new techniques such as the use of niello allowed for necklaces with brighter, more predominant gemstones. The Early Byzantine Era also saw a shift to distinctly Christian jewellery which displayed the new Christian iconography.

Timeline of non-classical European necklaces 
2000 BC – AD 400: Bronze amulets embossed with coral were common. In Celtic and Gallic Europe, the most popular necklace was the heavy metal torc, made most often out of bronze, but sometimes out of silver, gold, or glass or amber beads. 

AD 400 - 1300: Early European barbarian groups favored wide, intricate gold collars not unlike the torc. Germanic tribes often wore gold and silver pieces with complex detailing and inlaid with colored glass and semi-precious stones, especially garnet. Anglo-Saxon and Scandinavian groups worked mainly in silver, due to a deficit of gold, and wrought patterns and animal forms into neck-rings. In the Gothic period necklaces were uncommon, though there are a few records of diamond, ruby, and pearl necklaces. It was not until the adoption of lower necklines later in the Middle Ages that necklaces became common.

1400 – 1500: During the Renaissance it was fashionable for men to wear a number of chains, plaques, and pendants around their necks, and by the end of the 15th century the wealthiest men would wear great, shoulder covering collars inlaid with gems. Women typically wore simpler pieces, such as gold chains, or strung beads or pearls. By the end of the period, larger, more heavily adorned pieces were common among the wealthy, particularly in Italy.

1500–1600: Long pearl ropes and chains with precious stones were commonly worn. In the latter half of the century, natural adornments, such as coral and pearl, were joined with enamel and metals to create intricate pendants. Heavily jeweled, delicately framed cameo pendants were popular as well. Chokers, last worn commonly in antiquity, also made a resurgence at this time.

1600–1700: Few men in the Baroque period wore jewellery, and for women necklaces were unsophisticated, often a simple strand of pearls or delicately linked and embellished strands of metal with small stones. Later in the century, after the invention of new diamond cutting techniques, priority was for the first time given to the jewels themselves, not their settings; it was common for jewels to be pinned to black velvet ribbons. Miniatures also grew in popularity, and were often made into portrait pendants or lockets.

1700–1800: Portrait pendants were still worn, and in extravagantly jeweled settings. The newly wealthy bourgeoisie delighted in jewellery, and the new imitation stones and imitation gold allowed them more access to the necklaces of the time. In the early part of the century, the dominant styles were a velvet ribbon with suspended pendants and the rivière necklace, a single row of large precious stones. By mid-century colorful, whimsical necklaces made of real and imitation gems were popular, and the end of the century saw a neo-Classical resurgence. In the Age of Enlightenment gowns often featured a neck ruffle which women accented with neck ribbons rather than traditional necklaces, but some women did wear chokers inlaid with rubies and diamonds. Seed pearls were introduced to the United States during the Federalist Era, leading to an increase in lacy pearl necklaces.

1800–1870: The low necklines of the court gowns fashionable at this time led to the use of large necklaces set with precious jewels. In Napoleon's court that ancient Greek style was fashionable, and women wore strands of pearls or gold chains with cameos and jewels. In the Romantic period necklaces were extravagant: it was fashionable to wear a tight, gem-encrusted collar with matching jewel pendants attached and rosettes of gems with pearl borders. It was also common to wear jeweled brooches attached to neck ribbons. Some necklaces were opulent in that they were made to be dismantled and reconfigured into a shorter necklace, brooches, and a bracelet. Highly embellished Gothic style necklaces from England reflected the crenelations, vertical lines and high relief of the cathedrals. Empress Eugénie popularised bare décolletage with multiple necklaces on the throat, shoulders, and bosom. There was also an interest in antiquity; mosaic jewellery and Roman and Greek necklaces were reproduced. Machine-made jewellery and electroplating allowed for an influx of inexpensive imitation necklaces.

1870–1910: The Edwardian era saw a resurgence of pearl necklaces, in addition to a dog-collar style of necklace made of gold or platinum with inset diamonds, emeralds, or rubies. The Art Nouveau movement inspired symbolic, abstract designs with natural and animal motifs. The materials used - glass, porcelain, bronze, ivory, mother of pearl, horn, and enamel - were not used for their value, but for their appearance.

1910–1970: Chanel popularised costume jewellery, and ropes of glass beads were common. The Art Deco movement created chunky, geometric jewellery that combined multiple types of gems and steel. By the 1960s costume jewellery was widely worn, which resulted in seasonal, ever-changing styles of necklaces and other jewellery. Real jewellery that was common in this period included wholly geometric or organically shaped silver necklaces, and precious gems set in platinum or gold necklaces inspired by the time of the French Empire. Love beads (a single strand of stone or glass beads) and pendant necklaces (most often made of leather cords or metal chains with metal pendants) became popular and were worn mostly by men.

China

In Qing dynasty China, a court necklace called  (), was worn by the Qing dynasty emperors and other members of the imperial family. The court necklace originated from a Buddhist rosary sent in 1643 by the Dalai Lama to the first emperor of the Qing dynasty. The necklace is composed of 108 small beads, with 4 large beads of contrasting stones to symbolize the 4 seasons, and was placed between groups of 27 beads. The necklace was also practical as it could be used for mathematical calculations in the absence of an abacus.

Necklace with longevity lock pendant 

In China, there is a custom of wearing a necklace with a longevity lock pendant. These lock charms were sometimes personally tied around the necks of children by Buddhist or Taoist priests. The longevity lock is known as  () and is an important form of amulet for children for thousand of years in Chinese culture. According to Chinese beliefs, the  protect children from evil spirits and bad luck by locking its wearer's soul and life inside of the lock. The  is often made with precious materials, such as gold, silver, and jade, and having auspicious words carved on it. This form of necklace continues to be worn in present-days China.

The depictions of the keyūra was introduced in China along with Buddhism. The depictions of  in China, such as those found in Dunhuang, evolved in shape and styles showing the cultural integration of foreign (non-Chinese) culture and the native Chinese culture due to the special characteristics of its geography. The  eventually evolved from an ornament in Buddhist arts and eventually became an actual necklace by the Tang dynasty. The  then became a classical form of necklace in Chinese society throughout centuries. It continues to be worn in present-day, especially as a common hanfu accessory being used by Hanfu enthusiasts since the Hanfu movement. It comes in variety of styles, shapes, and materials.

Shell necklaces 
Aboriginal Tasmanian women have been making shell necklaces from maireener (Phasianotrochus irisodontes) shells for at least 2,600 years, with some major collections in museums. The continuation of the practice is being threatened by reducing supply, and sixth-generation Palawa woman Lola Greeno is concerned that the practice will die out.
