This superior triple strength hematite magnetic bracelet is made of crushed hematite formed into ceramic hematite beads. We have combined the magnetic therapy of hematite with the gemstone healing of Aventurine and Sodalite. Our magnetic bracelets are strung on 49 stranded stainless steel Accuflex wire and have a 5000 Gauss Gun Metal epoxy magnetic clasp. Magnetic bracelets are the strongest treatment for hand (arthritis tendinitis), wrist (arthritis, tendinitis, carpal tunnel), elbow (arthritis, tendinitis) and shoulder (bursitis, tendonitus, frozen shoulder) on the arm they are worn. However they will often help neck, back and knees. Determine magnetic bracelet size by measuring the circumference of the wrist and adding 3/4 inches.
