What are 10K and 18K gold? What is the difference between them?
The first thing we need to know is that the “K” refers to carats, which is the unit of measurement used to determine the purity of gold (Do not confuse it with “ct” which refers to the carats used as a unit of measurement for diamonds).
The highest purity grade is 24k, which indicates that the piece is made of 99.99% gold. However, because pure gold is very malleable and susceptible to scratches and dents, it is mixed with other materials such as silver, copper, or nickel, which provide greater durability and resistance, as well as allowing us to change its tone.
But what percentage of pure gold is in 18k, 14k, and 10k?
