odd...somewhere i had read about jade for virgo...i think it was in a book by linda goodman...
also, virgo is ruled by mercury and in vedic astrology stones for mercury include (but are not limited to): emerald, green jade, peridot, green tourmaline, tsavorite and green diopside...
but then, someone who is a virgo in western astrology might not be a virgo in vedic, so i don't know if that really helps...
lord, i'm out of it today! lol...sorry...i think i'm even confusing myself...
many blessings to all!!
p.s. hope it's ok i post this here...i do have cunningham's book, but did not reference it for this reply
p.p.s. i totally agree w/Pollux re: picking your own stone...i love aquamarine (my birthstone)...but it certainly isn't the only stone i love, and my personal favourite (today) is an ametrine piece i have in my collection...
