Gemstones represent energy in its most solid form. Each gemstone has its own energetic characteristics that allow us to distinguish one from another as do each of us have our own electro-magnetic fields that are in turn impacted by the energetic quality of each gemstone. When selecting gemstones, the most important guideline is that the stone is appealing to you. The body has a way of being attracted to a gemstone that is appropriate for use at the time, whether you consciously realize it or not.
