The dealer is azmeteorites. He has a variety of items on eBay, not just Moldavite. He does list Tibetan tektite that (per other posts in this forum) looks too shiny to be Tibetan, but since that seems to be what ALL the vendors are doing, I didn't count that against them. He does have a money-back guarantee, which was another reason why I thought that dealing with him would be a positive experience.

Their stone arrived with a card about Moldavite and other literature about rock shows, that I haven't read through yet.
