Yes. I think one of the most helpful beginner texts I’ve run across
is Joel Arem’s “Gems and Jewelry.” Arem and others have written
books you’ll want to acquire as you learn more, but this little
pocket-sized classic is one of the best. It’s a few years old now
and doesn’t have on the very “latest,” but if you learn
what’s in it you’ll be very well prepared to tackle thicker and more
up-to-date texts. It may be out of print and if you can’t find it
contact me direct. I discovered a few copies I’d purchased for
customer enlightenment tucked away in a cabinet last week.
