@rightwriter I would suggest not believing everything you’ve read on the internet. That “Or Emunah” site is highly questionable and seems to be more based on Eastern mythology than Torah. The “Kibitz” link is just trying to sell chintzy chotchkes. The only good source seems to be this Rabbeinu Bechaye which the Chabad site that quoted it stresses that the true healing is the Torah and Tahara.
I’m not sure what your agenda is, though it’s clear you have one. But other than one Rabbeinu Bechaye (who stresses that Torah is the ikkar and also seems based on the folk medicine of his time), there is no basis in Yiddishkeit that gemstones have some magical healing properties and can be used to supplement (or substitute) actual medical help.
