This is a truly hand-crafted (made on the bench!) soldering and all. This gorgeous South Sea pearl is about 12 mm. The hand-crafted pendant piece and chain are sterling silver. One-of-a-kind but can be custom ordered. I hand-selected this particular pearl because it was nearly round and almost white. The post design is a simple curve shape, to reflect the gentle cure of the south sea wave. Together, the pendant and the pearl create a beautiful natural harmony.
