A blue-green boulder opal from Australia is surrounded by my signature 18k botanicals, accented with diamonds and a freshwater pearl drop. The bail is on a hinge, fitting over pearls, beads or a heavy chain. This piece is sold.  A pendant with a stone of similar character can be made to order.  The price listed is approximate.
