14K Gold Filled & Sterling Silver
KOZAKH is our Demi-Fine jewelry line, sustainably handmade in 14K Gold Filled and solid Sterling Silver. 14K Gold Filled is made by pressure bonding a thick layer of 14K Gold to a brass core. The gold layer is 100x thicker than Gold Plating, and 20x thicker than Vermeil. It is the best alternative to solid 14K Gold. You can wear your Gold Filled jewelry 24/7 for decades without worrying about tarnishing or the gold layer wearing off, and it is easy and safe to clean!

Gold PVD

PVD, or Physical Vapor Deposition, is a cutting-edge process that utilizes a vacuum coating technique to deposit a layer of gold onto high-grade stainless steel. Used by luxury brands like Rolex and Cartier, PVD offers exceptional resistance to tarnishing and discoloration, far outperforming conventional gold-plating. Get the luxurious look and feel of real gold and the durability and hypoallergenic features of stainless steel with KZK Gold PVD! Learn more about all the different types of gold used in jewelry making here.
