[Sca-cooks] Precious stones to ward off evils

[Suey]

    Last week or so diamonds we discussed but not as stones to worn in 
rings on the ring or baby finger of the right hand ward off evil 
spirits, reduce a humor, poisons, polluted air or whatever. Spanish and 
English texts I have found list numerous stones worn but are rather 
general about the stones' powers.  I'd like to see something more specific.
    Further it would be fun to know what combination of stones were used 
when wearing two rings. For instance an emerald might be worn on the 
ring finger to ward off poison and the ruby on the baby finger for 
happiness, health and success.
    Then we need to know why one stone would be worn on this finger and 
the other on that one.
Anyone ever run across this type of info?
