24 Karat Gold is a term used to describe pure gold, which is 99.9% gold content. The "karat" system measures the purity of gold, with 24 karats being the highest possible rating. This means that 24 karat gold contains no other metals mixed in, making it the most valuable form of gold available. Due to its softness, 24 Karat Gold is not commonly used for jewelry that requires durability. Instead, it is often used in investment products, such as coins and bars, and in certain electronics and dental applications where high conductivity is essential.
