The earring hooks and connector rings on these earrings are silver plated. The turquoise crystals have an AB (aurora borealis) finish that make them reflect light. The earrings also contain white pearl seed beads, silver spacers and a white opal Swarovski crystal dangling from the bottom. The diameter of the earrings is just over 1/2" and the length from the bottom of the earring hook is 1". They include plastic backs. I also include a free handmade jewelry bag with every jewelry purchase. I don't charge for shipping within the 48 continental United States. If you live outside of that area, please message me and I can give you an estimate on shipping costs. Thanks for shopping!
