Our Metals


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!
