We're committed to using high quality chain, stones and materials. We use 14k gold filled or sterling silver chain, almost exclusively and all of our jewelry are nickel-free and hypoallergenic. While we try to photograph each piece as accurately as possible, colors may appear different based on which screen. Please appreciate the beauty of natural stones and that no two stones are exactly the same. If you have any questions about stones or component colors, please don't hesitate to talk to us!
