A necklace of 30 inches in length is commonly referred to as an opera necklace, and a necklace of 36 inches in length is commonly referred to as a rope or lariat necklace. A rope necklace is typically a long strand of beads without a clasp, whereas a lariat is simply used to describe a long necklace, beads or otherwise, with a clasp. Necklaces 40 inches and longer will hang at or below the navel and are often wrapped two or three times around the neck to form a shorter, layered effect.
