@daas-yochid I’m dismissive of Rabbeinu Bechaye as a source to state that one can, in contemporary times, use gemstones to heal or protect from injury or illness. If you read what is written, he seems to imply that the healing properties are based on the knowledge of the time, and that Teffilah and Torah work better as a medicine. I don’t know of any major poskim, mainstream or otherwise, that promote gemstone healing. If there were, I doubt Or Emunah would be forced to resort to that single shakey “haskamah” I mentioned earlier.
@CHOOSID That, of course, is a gem that has wonderful healing properties.
