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 beads are 9 carat gold, the pearls are fresh water pearls and they are mounted on sterling silver. Yum!
