@rightwriter The fox tooth is in the same sugya as the scary mask which I already commented on. Your questions about the significance of the Choshem stones was also answered, look it up in Rav Hirsch. There are multiple other Rishonim and Acharonim who discuss it, I’m sure you can find one or two in a Mikraos Gedolos.
What about when Bnei Yisrael had to gaze at the bronze snake to get healed?
Ayin Mishnayos mesachtos Rosh Hashonna (and the London School of Jewish Song song using those words).
Im sure there are plenty more sources in Judaism.
I’m sure there aren’t based merely on the fact that none of these gemstone salesmen mention them. The strongest source seems to be Rabbeinu Bechaye. All the other sources mentioned do not state that gemstones have healing properties, such as Avrohom Avinu which I mentioned in an earlier comment.
