Approximate Weight Notice: Due to the handcrafted nature of our jewelry and natural variations in gold alloys, listed weights are approximate. Minor differences may occur from piece to piece.
Square links, rounded into a smooth rope of gold.
The 4MM Solid Rounded Box Chain takes the square box link and rounds its outer faces, producing a smooth, near-cylindrical profile that reflects light in a continuous band rather than in facets. It is dense, heavy for its width, and unusually flexible. At 24 to 86 grams depending on purity and length, it spans everyday wear through full statement weight.
The rounded profile is what separates this from a standard box chain. Without sharp edges, the chain catches light along its whole length at once, and it sits comfortably flat rather than pressing a corner into the skin.
Every piece is XRF tested for purity and priced by its final weight, so what you pay reflects the gold that actually goes into your chain.
Available in 10K, 14K, 18K, 22K and 24K solid gold, with yellow, white and rose gold options on 10K–18K. Lock hardware varies by purity: 10K through 22K offer a Lobster Lock, while 22K and 24K pair with a secure M Lock.
