Also check out Your Gemologist (warning, it has audio that plays no matter what, so turn down your speakers — I turn mine completely off). This site features tons of information on properties of individual minerals, gemstones, and much more.
I found on the late Jeff’s Graham’s site that his opinion was the money you’d spend at a course could be better spent buying equipment and teaching yourself. He may be right but you’d need to be the sort that really can self- teach so you don’t just buy equipment then put in on a shelf for when you get a round-to-it. Read what Graham had to say on the subject and if you have an opinion, please send it in, or post a comment!
