I have used 5mm tube magnetized Hematite gemstone beads, silver plated heisi spacers and sparkling violet color swarovski crystal bicones to make this bracelet and strung with special strong beading elastic. It will fit a wrist up to 6 3/4". Magnetic Therapy is a wholly natural event. It is neither magic or medicine. Today in a world filled with prescription medicine, people are finding that there is a alternative. I have used natural occurring magnetic hematite gemstone beads and magnetic based pearlized beads in gold and silver color. The use of magnetic therapy has increased dramatically. Many sports medicine and physical therapists, massage therapists, neurologists, chiropractors and recommending magnetic therapy. Because you can wear my magnetic jewelry 24/7, the results are greater than magnetic products that are used sporadically. Here is a partial list of the condition magnets give relief: arthritis, acne, back aches, high blood pressure, bursitis, diabetes, carpal tunnel, chronic fatigue, fibromyalgia, insomnia, menstrual cramps, migraines, poor circulation, night sweats, tendonitis and MS. Most people notice results within 3-5 days, while others it may take a couple of weeks. The use of magnets should not replace treatment from qualified medical professionals. Consult a physician before using magnets if you have a pacemaker or defribrillator. I personally use them and find relief of pain and discomfort. I have necklaces, bracelets, chokers and anklets listed and will make pet collars on request. I will happily combine purchases paid together within a 7 day period. 5% GST Sales tax is required within Canada.
