in this last few Years since USA and Europe in crisis, the best buyer for pearl is India and China.
This 2 Country are the strongest buyer for pearl, China Take the High grade pearl, India take the lower and middle grade pearl.
any quantity you offer, they will take, 5-10-25-50 kg they will buy, hope your buying power still strong till the future years.
I Like to make transaction with them, since they are fast in transaction and experience in International pearl price.
Good Luck to You All
All the Best
