    nothing changes. Gem must be durable. It is very difficult to find
    emerald without some kind of a fracture and decision was made,
    probably in smoke-filled back room, to allow oiled, and otherwise
    treated stones to be sold as gems. But that is bowing to the industry
    pressure. I use gem in gemological sense, not in commercial one.
