Just came back from New York, where I took the "Pearl Grading Lab Class". Somehow I managed to ignore the word "grading" and expected to take part in experiencing the lab facilities we learned about in the GIA pearl course.
I also realized about two minutes before the class started that it was open to all and not only to the graduates of the course. So I ended up quite disappointed.
In fact, the only new detail I learned from the lab (actually more a seminar) instructor was that some Tahitian farmers are growing Tahitian pearls in Japan, in order to gain mirror-like luster. Does anyone here knows more about this?
While in NY, Eli and I walked into the Mikimoto store on 5th Avenue. They had multicolor strands that were mixed SS, Tahitian and FW!!! - but big perfect FW.
They also had several Tahitian strands with a very sharp mirror luster. Were those the "Japanese Tahitian"? Is it possible to grow black-lipped in cold water?
To sum up this day, I met nice people to whom I highly recommended our forum, Eli was allowed to sit in their computer room during the class while it snowed outside, The snow was quit an experience for me, coming from a generally snowless country.
