Is this solid 14k white gold?

The pendant and chain are described as 14k white gold. White gold is usually rhodium plated for a bright finish, and that plating can wear with time.

How much diamond weight does it have?

About 1 carat total diamond weight across the cross. The listing does not state the individual stone count, cut grade or color.

How big is the cross?

The pendant's dimensions are not given. The design is described as softly rounded rather than large or bold, so expect a moderate, wearable size.

Can I wear it every day?

Yes, but the cable chain is described as delicate. A fine chain is more prone to snagging and stretching than a heavier one, so take care with knits and seatbelts.

A diamond cross is a common gift for baptisms, confirmations and graduations. Its classic shape and white gold suit most tastes.

How should I clean it?

Use mild soapy water and a soft brush, rinse and dry fully. Avoid harsh chemicals and ultrasonic cleaners, which can loosen stones or dull the rhodium.
