14kgf

"14kgf" ​​is an abbreviation for "14K Gold Filled". This material is made by crimping K14, which is equivalent to 5% of the total weight, onto metal such as brass. 14kgf is reinforced with a thick layer of K14 on the surface, making it more durable and lasting longer than gold plate (KGP). The material is said to be less likely to cause allergic symptoms.
