Is this chain solid gold or plated?

It is 14K yellow gold, so the gold runs through the piece rather than sitting as a plating over brass or steel. That means it can be polished and worn for years without flaking.

How does 14K compare with 18K for a chain like this?

14K is harder and more scratch-resistant, which suits a daily-wear chain. 18K has a richer yellow color but is softer and dents more easily.

What does a 26-inch length look like when worn?

It hangs below the collarbone, roughly at the top of the chest, and sits over a shirt collar. For a closer fit, a 20- to 22-inch chain is the usual choice.

Will the box clasp stay closed?

A box clasp with a safety catch is standard on Cuban chains and holds better than a lobster claw under weight. Check that the catch snaps firmly and have a jeweler tighten it if it loosens.

Can the chain be resized?

A jeweler can shorten it by removing links, but each removed link is lost gold and the work costs money. Buying the right length up front is simpler.

How should I care for a 14K gold chain?

Wipe it with a soft cloth after wear and store it flat or hanging to avoid kinks. Avoid chlorine and harsh cleaners, and have the clasp checked once a year.
