This necklace can be worn casual without the pendant or attach the pendant for a formal occasion. I make each piece of jewelry individually using high power magnetic hematite beads with super strong magnetic clasps. Custom orders are always welcome. Magnetic jewelry has been known as a drug-free method for decreasing pain caused by tennis elbow, osteoarthritis, fibromyalgia, and other painful conditions for many people. Although magnetic therapy is not for everyone, studies have shown positive results with many who have tried it. I bought my first piece of magnetic jewelry for the simple fact I thought it was beautiful.. At the time, I was experiencing joint and back pain and lack of energy. Within a few days of wearing my magnetic bracelet, I realized I had more energy, and my joint pain had diminished greatly. I thought it was a coincidence at first but soon came to the conclusion the magnetic bracelet was the cause of my relief. Give it a try....what do you have to lose except pain! (Magnetic Jewelry should not be worn if you have a pacemaker, electronic device or are pregnant.)
