I received a post from my friend Dr Gustaf Mamangkey, which I thought to share. Dr Mamangkey is head of the Marine Science Study Program at Sam Ratulangi University in Indonesia.
His thesis is published and is quite a read, but the abstract is thorough.
Something all might find interesting is his latest publication detailing his experimentation with UV-Vis spectroscopy and how it can be used to determine and describe different pearl colors, origin, treatments and enhancements, and as a quantitative measure of pearl lustre.

It would be interesting to know if he would be able to detect the giant clam nuclei (tridacna squamosa) that Jerry Ventouras from Paragon pearling and Australian netmakers in Perth was using as a cheap substitute in place of the Missisipi clam shell nuclei that everyone thought they were buying.They were purchased from vietnam from a government run bead making factory and imported into Perth under a false shell variety.They are a very white bead and they are very hard and tend to overheat the drill bits resulting in them snapping whilst trying to strand the pearls
Professor, has Dr. Mamangkey given you any indication that these mantle experiments have anything to do with the new generation of beadless saltwater pearls from this part of the world that are turning the natural nacreous pearl market on its head?
No because DR Ma Monkey is too busy working with Sir Arther flapjack
