It depends on the necklace. 18k gold is purer than 14k gold because it contains a higher percentage of gold. This makes it more valuable but less durable. Generally, 18k gold is viewed as a superior choice for black-tie or red carpet necklaces and fine jewelry, whereas 14k gold is better for necklaces worn on a daily basis.

A 14k gold chain necklace typically ranges in value from $200 to $2,000, though it can be worth more depending on its quality and size. The price is influenced by the weight of the gold, any diamonds or gemstones included, and sometimes the brand or designer affiliated with the design.

The best indication that a gold necklace is real is if it features a small marking stamped into the gold that indicates its purity. The most common hallmark is the karat mark, which shows how much pure gold the item contains.

Yes, you can wear an 18k gold necklace every day, but it might not be the best choice. 18k gold is softer and more prone to wear and tear compared to 14k gold. 14k gold is both more durable for everyday wear and less expensive, making it the more practical option.
