Is this chain solid gold or plated?

It is rose gold plated with a 14k designation on the listing. That means a base metal core with a rose gold layer, not solid 14k gold throughout.

How wide is the chain?

The chain is 3mm wide. That is a mid-weight Franco link that reads bold on its own and still fits under most pendants.

Will the rose gold color fade?

Plated chains can fade or wear where they rub against skin, especially with sweat, perfume and lotion. Keeping it dry and storing it in a pouch slows that down.

Can I wear it in the shower or to the gym?

It is better not to. Water, soap and sweat speed up plating wear, so take it off before showering, swimming or heavy workouts.

How does it compare with a solid gold Franco chain?

A solid gold Franco chain lasts decades and can be repaired or resold, but it is far heavier and more expensive. This plated version gives the same look with more care needed.
