Hi Catherine,
    Here is another one that might help:
Fernie M.D., William T.  The Occult and Curative Powers of Precious Stones,
Rudolf Steiner Publications, Blauvelt, New York, 1973, originally published
in England in 1907 as Precious Stones: For Curative Wear; and other Remedial
Uses; Likewise the Nobler Metals.
    Hope this helps.
