I finished the course in just over an hour. The course is nicely done but basic. Pearls as One is definitively much more complete...but I believe ALL pearl education is a must! Good job by Dr Laurent Cartier and SSEF
I finished it in about the same time and have the same impression, Douglas. Pearls as One is more thorough. I have issues with the natural pearl sections in both, but when I remind myself it's an ID guide for cultured pearls and not a treatise of pearl formation and/or their causes, it's all good.
Etiology and pathology are quite boring subjects to the average individual, but I would have hoped the labs took it a bit more seriously.
Yes, advanced courses are a good idea for those who are more inclined. In most industries, R&D is spearheaded by the industry itself. Not so much in pearl culture but for it's marginal nature and technological protectionism. In the natural world, marketable or not marketable are irrelevant terms. The average consumer and most pearl markets/farms have no real interest in the greater understanding of epithelial behavior beyond what they already know.
Too bad too, because I'm probably the only person on the planet who can produce natural pearls on demand (especially at the point of onset) and able to ship them properly live or fixed for high level analysis.
I don't look upon pearls as baroque, keshi or dimpled. I see them as periostracial, myostracial, xeno or homogeneic, sterile or non-sterile, anuclear, mononuclear or polynuclear. Every pearl is observed and recorded post mortem for it's type and onset.
I may publish all this one day when my legs give out, but for now I'm perfectly content to continue my field work instead.
