The signature rolo chains are most popular to pair with your sterling pendant! We offer three different chain widths- 3MM, 4MM, 5MM. Each width is available in 16", 18" and 20" lengths. We recommend 3MM & 4MM widths with mini and small size pendants. 4 MM and 5MM is recommended for medium pendants, and we suggest 5MM with large pendants. Crafted of .925 sterling silver.
