I made a big collection of these beauties for Francis Nation Shop in New Zealand and me being my prolific self I made far to many. The green beads are South African Opal. They are a bit porous so they absorb the wearers skin and darken with time which I love- a stone that looks richer and deeper with wear is an amazing treat. The pendant is made from silver, fresh water pearl and an opal bead. The long earrings come with your choice of hooks or hoops (let me know your preference when you buy them) and are made from opal, fresh water pearls and gold filled wire. the trio of earrings come on silver hoops- The beads are 9 carat gold, the pearls are fresh water pearls, the little metal blob at the base of the opal on a chain is 9 carat yellow gold.
