Red Jasper is an opaque stone from the Chalcedony classification, due to its microcrystalline structure, containing iron impurities resulting in the red colouration.  

Red Jasper is a very powerful root chakra associated stone.  Your root chakra governs basic survival and existence, as well as being the foundation of your energy body.  Red Jasper can assist with the energetic boost you are seeking to get those physical tasks done that you have been putting off, or the spark of support you need to commence or keep going with a new health and or exercise regime.  In deep meditative practice Red Jasper can give you comfort with feelings of safety and refuge.
