All jaspers are members of the quartz family. Their microcrystals are arranged in a massive granular formation and can contain as much as 1/5 foreign material; hence the huge range of colours and forms possible and why so many different forms are found around the world. Jasper is a hugely useful stone, with wide-ranging uses. In general they are all solid and earthy, helping us deal with the day-to-day realities of living an earthly existence. Their colour range and patterning bears relation to the areas they might best be used, according to chakra centre spectrum colours and their symbolic patterning.
