Did you happen to capture the pearl? I'm curious as to how you know the weight of the shell...did you bring it to the surface? Technically, oysters never grow that big, but giant clams, tridacna gigas, grow extremely large...so that must be what you mean, right? If you have photos, it would be interesting to see them. Soon a 5 pound tridacna gigas pearl, the "Palawan Princess", will be for sale at Bonham's auction, this Dec 6. I wonder what the hammer price will be?
