We suggest buyer buy in small quantity like 250 grams – 300 grams, 10-12mm, it is easier for us to found and calculate the price. so we can work each other in good price.
Grade A and B we mix, it is difficult for us to sell A grade only. we commonly mix the package in ABC grade, with composition AB 50% and C50% or sometimes depending buyer request price or pearl in stock. i ma sure if you are experience with international pearl trade you will understand this.
for golden pearl we have, for black and peackok it is not from Indonesia, it is from Tahitian
