As with most stones, there are multiple uses for Chrysocolla. The most commonly mentioned use seems to be as a communication aid. My primary use for this stone is to soothe me when I am in pain. I discovered Chrysocolla’s usefulness as a pain reliever when I suffered from TMD (affecting the jaw and neck) symptoms for a time a few years ago. I took naproxen, used a heating pad, and used this stone when the pain flared up. Thankfully those TMD symptoms eventually went away. However, I do have the occasional migraine. Last night I felt a migraine coming on, and I instinctively started massaging over my sinuses with the pictured stone. I believe I also held it in my hand as I ran my fingers over my scalp (the same hand). The migraine retreated after maybe around 15 minutes of doing this. Normally I have to take Excedrin Migraine, apply a cold pack to the back of my neck, and drink a Coca Cola to deal with a migraine. Getting rid of it before it got bad by massage with a stone was rather impressive to me. Sure this is not the most convenient method if you are out in public. I can imagine the looks a person would get rubbing Chrysocolla over his or her face while at work. I definitely would not recommend relying solely on a stone if your pain is severe. However, I wouldn’t hesitate to pull this stone out to deal with minor aches or as a facet of a treatment plan to cope with stronger pain while at home. That all being said, this is what works for me. I am not a medical professional. If you are seriously suffering, seek professional help. Blessed be, y’all.
