History of Necklaces and Pendants
A necklace is a form of jewelry worn suspended around the neck. It is most commonly made in flexible forms such as a chain, as a string of beads, pearls, gemstones, or other natural materials, or made of a more inflexible band of metal embellished with gemstones, pearls, beads, or other techniques such as engraving, filigree, repoussé, granulation.
For example. Lengths of necklaces vary, and specific types related to extremes in length range from a short choker or dog collar necklace that fits right around the main portion of the neck to a longer neck chain or string of beads called a sautoir, sometimes worn hanging down to or past the waist.
A pendant is an ornament that is suspended from another piece of jewelry such as a necklace, neck chain, ribbon, brooch, bracelet, or earring. Pendants take many forms including large gems or pearls, cameos, crosses, lockets, amulets, or watches. Amulets as pendants have been most significant as one of the first forms of prehistoric jewelry.
As pendants, amulets retain an unprecedented popularity in the early twenty-first century as good luck charms, as talismans, and as protection from the evil eye or any number of other perceived disasters or supernatural forces. Pendants are frequently made to be detachable so they might be used on different necklaces, or made with a pin-back so they might also be worn as a brooch.
