All of the gemstones found here are natural and free of dyes. Some may be heat-treated to produce more vivid, vibrant colors. The wires used are copper, sterling silver (.925), fine silver (.999), gold filled, and rose gold filled. The wire is sourced from a US company, and all materials are nickel-free. Stainless steel or gold ear wires are available upon request. I’m happy to do what I can to accommodate your needs.
