| As in anything, the key to understanding is frequent and intense exposure. Thanks to Caitlin for posting the pictures for the benefit of everyone here.
Comment from my natural-pearl friends in the South Seas was that neither pearl in my last post had orient, also that the photo of Tom's pearl did appear to have an incomplete nacre layer. Substitution of pure, translucent conchiolin for aragonite, however rare and potentially beautiful, would seem consistent with this. So still a bit of a head scratcher… |
