Dear All, Thanks you for your kind answers, I have really very difficult to converse in English and misunderstandings are possible. Caitlin, also I doubt that anyone has really done the statistics, but it is strange that no one recorded finding of many pearls in the same shell, also in the...

In the Pearl Rodeo on June 2010 were fished 98.000 oysters but is not write how many pearls they found, it can be in interest to know the percent of pearl production in wild Pinctada (I think radiata). Someone know if in 2011 there was another pearl rodeo? Gianpiero
