Materials Matter 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.
