I looked at several “healing gemstones and crystals” books about the subject, and each book recommends something different. One book recommends onyx being placed on the each ear for 15 minutes, where a few other books don’t even mention onyx but recommend quartz crystal, amethyst, or another gemstone. Where should the gemstone be placed, worn, or should an elixir be made?
i have high doubts that anything of that sort will work. Try a hearing aid crystal.
Stones or crystals do not have any magic powers. (unless radioactive)
Although I do not know the answer to your question, I thought I would pass on this formula which has had success healing deafness…the b and b tincture

be sure to use organic or wildcrafted herbs for best results. Making an herbal tincture would be best.
