K14gf is a gold-plated finish in which 14K gold makes up 1/20 of the total weight. It is pressed and will not peel off even after long-term use. Since you can easily enjoy the luxurious shine of gold, many brands in Europe and the United States use it as a serious jewelry material.
In addition, since it is nickel-free, it is a hypoallergenic material, so people with metal allergies can use it with relative peace of mind.
