Product information
Description
A 1.2mm round Venetian box chain in 14K gold filled -- the Venetian box (or round box) chain is formed from square links rotated 45 degrees to create a rounded, uniform profile. It lays flat and smooth with a clean, modern look. Polished yellow gold, lobster clasp. Available in 16, 18, and 20 inch lengths.
Gold filled means 14/20 -- a thick layer of real 14K gold bonded to a base metal core. More durable than gold plated and will maintain its finish with proper care.

What affects the price of box chains?
Metal, width, length and whether the chain is solid decide the price. Gold karat (10K or 14K) costs more than sterling silver or stainless steel, and a wider, longer chain uses more metal. Use the Price filter on this page to set a budget.
Which box chain styles are most popular?
Fine sterling silver box chains lead the list. Thin styles around 0.6mm to 1.25mm are at the front, alongside 10K white gold and 14K yellow gold box chains. Polished stainless steel versions in black, gold-tone and plain finishes follow close behind.
What width of box chain should I choose?
Choose under 1.25mm for a pendant, wider for a statement. Fine widths like 0.8mm or 1mm sit quietly under a small pendant. Stainless steel styles from 3mm to 4mm give a bolder, more visible look on their own.
Can a box chain hold a pendant?
Yes, a box chain carries a pendant well. The square links hang smooth and even, so the pendant sits cleanly. Match the chain width to the pendant bail, and pick a thinner chain for a delicate pendant so the pair stays balanced.
What is the difference between round and 8-sided box chains?
Both are box-style chains, but the link shape differs. Round box chains have a smooth, softly rounded profile, while 8-sided ones are diamond-cut, with facets that catch more light. Both appear here in sterling silver.
How do I care for a box chain?
Wipe it with a soft cloth and store it flat or hanging. Keeping it unknotted protects the square links from kinking. Silver can tarnish over time, so store it dry and apart from other pieces. See our jewelry care guide for more.
