Firefly 7848-MC Gazelle Collection European Glass Crystal Earrings Intricately embellished mosaics are inset with a combination of European glass beads, brass and German silver wire. Findings are brass that has been silver plated and then antiqued. French ear wires are either made of sterling silver or gold fill. Posts are made of surgical steel. The lever back earrings are on high quality Euro wires, which are either antiqued brass or silver-plated antiqued brass. Variations in European Crystals: There are slight natural variations in the colors of the European crystals that we use. We are unable to control the variations of color in the stones; we do not guarantee that all the crystal stones will be an exact match. Jewelry Care & Cleaning: Please clean our jewelry with a soft cloth. Chemical baths will strip the beads of coatings and destroy the finish on the metals. We recommend putting on perfume and moisturizer before putting on the jewelry, because the chemicals in those can damage the finishes on the jewelry. Handmade in Guatemala: The Firefly Mosaic Jewelry Design Studio is located in Oakland, CA. Founder Edward Rudnicki co-designs the jewelry with lead designer, Juan Carlos Chavajay in Santiago Atitlan, Guatemala.
