I have many kinds of opals; various quality. I was wondering what is the best way to go about selling some. Advise welcome. I live in desert , far away from towns. Im not sure about selling on net by piece. Id like to sell some small bulk , say 20 light opals, 25 fire opals at a time, perhaps some commons, some blue opals and a couple of boulders. Any leads? I dont want to sell all, i just want to help my niece finish college.
