A pendant is the part of a necklace that hangs from the chain. Some necklaces feature a single pendant or talisman-like amulet, other necklaces are virtually strung with pendants, often of graduated size (largest at the bottom, with successively smaller sizes on either side). Solitary precious gemstones, as well as settings holding clusters of jewels such as diamonds, rubies, and emeralds, are common, if expensive, types of pendants. Other pendants are simpler, such as lockets bearing a loved one’s photograph or lock of their hair. Cameos can also be worn on necklaces as pendants, and during the Victorian Era, micro-mosaics were all the rage.
