Defining Pearl and Other Neckace Lengths
The chart below shows common names for pearl necklace lengths. Crossing over into bead strands and chain designs, the terms sometimes have a different meaning. For example, a 22" tied chain design is called a lasso, and a 36" to 48" tied design is called a lariat (not the same as the 48" or longer strand of pearls also called a lariat).
