Osmium is both the densest and the rarest element that you can dig out of the Earth. It's so hard that it's used (as an alloy) in places with constant pressure and wear, like the tips of fountain pens. One single cubic inch of this stuff weighs nearly a pound, and were you to somehow get a cubic foot of it, it would weigh over 1,400 pounds. Good luck with that, though: last year, the entire U.S. osmium production was only 165 pounds.
Sodalite and dioptase can lower high blood pressure. Blood pressure is regulated in the heart chakra. Place either of these crystals on the heart for 15-20 minutes per day. Carry or wear them as needed.
Carpal tunnel is due to excessive pressure in your wrist which causes inflammation and swelling. Applying essential oils on the area can reduce pain and inflammation. It is also advised to avoid positions that overextend your wrist, and to wear splint that holds your wrist still while you sleep to help relieve nighttime symptoms of tingling and numbness.
