This is an exquisite necklace comprised of a floating opal pendant with 18k gold plate setting. The opal pendant dangles from a genuine amethyst rondelle rosary style chain. The chain is 24k gold plate. I finished the necklace with a secure gold filled lobster claw. The amethyst compliments the fiery opal that flashes with many different colors. Simple and classic! The necklace measures 18". The pendant measures 3/4" by 1/4". Your necklace will ship insured and will arrive safely in a new gift box. Thank you for visiting Blossoms and Bluebirds!
