Our Chain Sizes Typically Start At 18 Inches, Offering A Versatile Beginning For Your Jewelry Journey. For Those With A More Robust Neck, We Recommend Starting With a 20-inch Chain For A Chic Choker Appearance. It’s Essential To Note That Thicker Chains, Like Our 19mm Options, Snugly Encircle The Neck, So Be Sure To Size Up To Achieve Your Desired Look.
