Questions about this piece

Is it solid gold?

Yes. Karat gold options are gold alloy all the way through, not plated or filled.

Will gold tarnish?

Karat gold does not rust, and in normal wear it does not tarnish. Lotion and soap film can dull it; warm water, a drop of mild dish soap, and a soft brush bring the shine back.

Can I wear it in the shower or pool?

Take it off to swim, bathe, or use a hot tub: chlorine in pools and hot tubs can weaken karat gold alloys over time. If it gets wet, rinse in clean water and pat dry.

Will a pendant fit on it?

It will if the pendant's bail, the loop the chain passes through, is wider than the chain (0.5 mm on this style) and the clasp end can pass through it. An enhancer bail, which opens and clips on, gets around a tight fit.

How fast will it arrive?
