Pearls Round
Can a 2-pearl oyster in it?
I know how its done and all .. but what if two bits of sand got into the oyster, which in turn only two bits of sand to a pearl or two? What if there was already a nice pearl, round in an oyster and other grain of sand falls, it is going to be another pearl?
Yes, it can happen, but is extremely rare.
