STUDY!!!!!!! Get a book. Go to a library. Go to a museum. Talk to a gemologist at the nearest Natural History Museum. Go to the reference library tab at the top of this web site and read the articles. Take advantage of the resources right here that are free. We can't do it for you. Sorry if I sound so cranky. I've been bed-ridden for nearly six months, but I've managed to identify nearly 1,000 stones for my private collection, without the use of a gem lab. I have some equipment, some reference books, and the material from the reference library here. I've spent less than $500 over the course of five years on equipment, some of which I consider a luxury, because I can't get out right now to the high school science lab (for a microscope).
