Hi, I would like to post some pictures of Opal cutting, Polishing, equipment, and then someone could kindly tell me what the equipment is, and a rough idea what they are worth second hand, and what part of the forum should this go in?, and I have 5 posts but don't seem to be able to upload JPEGS? please help, I cant sell any of it, because I don't know what it is, and what it is worth. thanks
