Oh My Australia.... a 20 mm round, white south sea pearl ....magniliquence! Golden south sea pearls from Indonesia and Myanmar have a minimum size of 10mm and a maximum of 20 mm! A white south sea pearl of this size is extremely rare. Do you have a picture of this triton among the minnows? I can arrange to have this royal pearl professionally appraised.
