These are the most glorious pearls I can remember seeing. What wouldn't I give to own even one. More would be better though Just love them. You are very lucky. I realise you have worked hard to get them all but still so lucky.
Thought to remind everyone just how small P. maculata is. The brightest and most golden shell in the sea happens to be among the smallest, if not the smallest.
But there are clearly localized populations, sub-speciated on remote atolls (such as Penrhyn in the Cook Islands and the much smaller Ahunui in the Tuamotos?right, loloperle?) where it becomes a viable pearl producer.
Latest DNA shows Pinctada maculata to be the direct ancestor of three very noble Pinctada species: P. fucata/martensii (akoya), P. radiata (Persian Gulf) and P. imbricata (Ceylon), all belonging to the family of smallish pearl oysters with toothed hinges. I guess we now know where the 'orient' in 'oriental pearls' really originates!
According to locals farming of P. maculata on Penrhyn was attempted (along with P. margaritifera) in the 1980s but the atoll is simply too remote, and the size of the shells too small to have sustained any longterm effort. Not to mention the Cook Islands' prohibition of foreign ownership.
