Is this real gold or plated?

It is solid 10k yellow gold, stamped 10k, for both the cross and the rope chain. It is not plated or gold-filled, so it will not tarnish or fade with wear.

How big is the cross?

The cross is about 1 inch long and weighs roughly 2.3 grams. It is a small, understated pendant rather than a large statement piece.

Which chain length should I pick?

18 and 20 inches sit near the collarbone, 22 and 24 inches fall to the upper chest, and 26 to 28 inches hang lower over a shirt. Pick based on where you want the cross to rest.

Can I wear it in the shower or to swim?

10k gold does not tarnish or discolor from water, so showering is fine. Chlorine and harsh soaps can dull the finish over time, so rinse and dry it after pool or ocean use.

Is 10k gold good quality?

10k is 41.7% gold, the minimum usually sold as real gold in the US. It is durable and affordable, but it is less yellow and less valuable than 14k or 18k.

What comes with the necklace?

You get the 10k gold cross pendant and the 10k rope chain in the length you choose. A gift box or pouch is not stated, so ask the seller if you need one.
