One of the most important stones to protect against negative energies. Life is lived more intensely under the influence of this adventurous stone. Encourages risk taking and change. It shows whats blocking your spiritual growth and enhances ones willpower. I bezel set the gemstone in .999 highly polished sterling silver around the gemstone and .925 sterling silver for the backing and the ring shank. I'm a one woman shop. I use only the finest materials from long standing companies.
