What stone would help pain and stiffness in the legs?

Green is primary color associated with healing stones used for physical and/or emotional focus in soothing/ pain relief: bloodstone, tourmaline and fluorite. Moss Agate is thought to be anti-inflammatory. Amazonite, Green Calcite, and Aragonite are popular for soothing /healing bone and supporting circulation. Aragonite helps with muscle elasticity/ spasms; calcites, purple fluorite, magnetite/magnesite for joints. As I consult 'The Crystal Bible' by Judy Hall, I also find Azurite and Rhodonite listed for joints in the quick reference section with diagrams & listings of corresponding body systems/organs.
