Features: 1) SA series 2) Material: semi precious stones 3) Size: 32 Functions: 1) Pain relief: The iron in your blood is attracted to the magnets which increases the blood circulation around the magnet and through out the body. Because of the increased circulation of blood, the endorphins (the bodies healing warriors and natural pain relievers) in your blood are forced to run rapidly through the body and are drawn to the problem area 2) Increase healing: The magnetic force stimulates the flow of nutrient rich blood to the injury site and throughout the body, which would otherwise be hampered by local constriction and inflammation 3) Increased energy levels: The increased blood flow forces endorphins to run through the body more rapidly which increases your energy level. Endorphins are in your body to give you energy, increase healing and to relieve pain 4) You feel better all over People use magnets for carpal tunnel, fibro-myalgia, diabetes, arthritis, stress, tennis elbow, headaches, tendonitis, general body aches and pains, improving blood circulation and restoring a more restful sleep. All the pieces of jewelry made have the strongest little 5000 gauss magnetic clasp or strand. They are 5 times stronger than most refrigerator magnets and because of the strength they snap right together without any effort. They are all strung on 40-pound test flexible wire coated with plastic so they won\'\'t break or rust. Jean has been making these for about 3 years now and has had excellent results with strength and durability of the jewelry and wellness of our customers\'\' bodies.
