Is this chain solid gold or plated?

It is solid 14k gold, not plated or gold filled. The color runs through the metal, so it will not wear off to a base layer.

What does 2mm mean for how it looks?

2mm is a thin, light cable chain. It reads as delicate on the neck and works well alone or with a small pendant.

Where does a 22-inch chain sit?

22 inches usually falls at or just below the collarbone on most adults. It sits lower than a 16 or 18-inch chain.

Can I wear it every day?

Yes, solid 14k gold handles daily wear and water better than plated chains. Thin 2mm links can still kink if pulled hard, so avoid catching it on clothing.

Can I put a pendant on it?

A light pendant suits the 2mm cable links. A heavy pendant can stretch thin links over time.

Is it worth choosing over a plated chain?

If you want a chain that lasts, can be repaired and keeps gold value, solid 14k is the better long-term buy. If you want a bold look at low cost, plated chains offer more size for less.
