Note that I am avoiding New-Age symbolism, concentrating on more general European symbolism, and ancient rather than modern symbolism. This is particularly difficult to do in regard to gemstones, since most of the web-pages which speak of gemstone symbolism are New-Age "crystal healing" pages. I am not interested in aetheric vibrations, but in meaning.
