Our charms, rings and stud earrings are made of 18k gold vermeil and sterling silver. Our 18k gold vermeil is extremely durable. It’s made with 2.5 microns of gold, 100-200 times more gold than a lot of plated jewelry on the market. Our chains are made of gold-filled (gold mixed with silver) rather than plated. Gold-filled chain has up to 25 times the gold found in plated chain and is made to last.
