I use sterling silver, Thai Karen Hill Tribe pure .999 silver, 14kt gold filled, brass, copper, pewter, silver plate and gold plate metals. I use genuine natural pearls, NOT glass pearls. I use shells, wood, coral, Swarovski crystals, Bali sterling silver, gems, semiprecious stones, 22kt vermeil gold over sterling, millefiori, cinnabar from China, glass, resin, acrylic, lucite and more for beads. Earrings can usually be lengthened or shortened if you need a different length. I can change earwires to clip ons, leverbacks or posts if you ask me to. If you have a certain design, content or stones you need for a special order or need several pairs of earrings for gift giving contact me and I can give you an estimate. Hope you enjoy my handwork. THANKS FOR LOOKING.
