All 3 pieces are made of genuine Swarovski Austrian Crystals. The AB (Aurora Borealis) coating on the crystals brings even more vibrant color, as the crystals gently pick up the colors around them. They are accented with Clear crystal rondelles that sparkle like diamonds. All silver used is .925 Sterling Silver. The clasps on the necklace and bracelet are easy-to-use lobster clasps with an extender that allows you to adjust the length. The earrings come with Fishhook Earwires as pictured....but we'll gladly switch it to Ball-post Dangles, Leverback or Clip-ons. Just put a note for us when you checkout!
