Question: is 10 karat gold worth buying?
Answer: High fineness jewellery has greater value, and is more tarnish resistant. Lower fineness jewellery, like 10-carat, is more affordable and also more hard-wearing. 10-carat is hard wearing and affordable but may tarnish. ... This means 10k gold would be a popular choice for jewellery, and gold items likely to get worn down.
