18k gold is a popular option when it comes to jewelry because of its durability and luxurious look. It is made up of 75% pure gold and 25% alloys, such as silver, copper, nickel, or zinc. Compared to 14k gold, which is 58.3%, 18k gold has a higher percentage of pure gold, making it more expensive. However, it is still considered a very durable metal that can withstand everyday wear and tear. 18k gold jewelry has a richer color than 14k gold, which gives it a luxurious and high-end look. It also offers the same resistance to tarnishing as 14k gold, so you won’t have to worry about it losing its shine over time. 18k gold is a great choice for anyone wanting to invest in quality jewelry that will stand the test of time.
