Is this real gold or plated?

It is white gold plated, not solid gold. The plating gives the white gold color over a base metal, so it will not have the resale value of solid 14k or 18k gold.

How wide is it and how does it sit on the neck?

It is 6mm wide and 18 inches long. That is a chunky tennis look that rests around the collarbone and shows clearly under an open neckline.

Are the stones real diamonds?

The listing specifies diamond stones in a micro clustered setting. Ask the seller for clarity and carat details if you need them for insurance or a gift.

Can I wear it every day?

Better for occasional wear. Plated finishes thin out with sweat, perfume and friction, and a 6mm clustered necklace is heavy for all-day use.

How should I clean and store it?

Wipe with a soft dry cloth after wearing and keep it in a pouch away from moisture. Avoid ultrasonic cleaners and harsh chemicals, which can lift the plating.

Does it come in other lengths or gold tones?

This version is 18 inches in white gold. GLD offers 14k and 18k options, so check the brand's other listings if you want yellow gold or a different length.
