I’m looking to develop a business selling colored stones to the
trade. I have access to good rough and to cutters, both “American
precision” cutters and good overseas cutting houses. I’m not sure
quite how to determine what stones and cuts and sizes are in demand
and how to price. I have looked at the prices in the Stuller catalog,
but don’t know where most jewelers source their stones, nor whether
they would be receptive to new sources. Can anyone help?
