I am not dealer and generally have as much love for dealers, as for stockbrokers, lawyers, travel agents, real estate agents, money changers and bankers . I.e. where value proposition comes from intermediation. Good thing is we are in age when thank you to: Steve Jobs and Bill Gates, Pierre Omidyar and Jeffrey Bezos they are almost extinct.

However, I will pass you name (via e-mail) of dealer i trust who has beads in Singapore

Good luck
