Hubert Bari, author of 'The Pink Pearl' is currently writing a similar book on abalone pearls. He acquired quite a large collection from NZ Natural Pearls (forum member) some time ago as part of his research.Speaking of book: is there any on abalne pearls as there is on conch ('The Pink Pearl')? These blues seem to be taking their place on the pearl scene, and not just on this forum.
Peter,
Is that last photo laminates? Is that used for inlay, rather than cut whole shell?
