Jasper is cryptocrystalline quartz with colored impurities. Cryptocrystalline means the crystals are too small to see except with a powerful microscope. Jasper crystals are fibrous and interwoven, making the material very tough compared to chert, in which the crystals are more blocky. Most jasper is red from iron oxide incorporated into it. Brown and green are from a mix of iron and other metal oxides. Black is usually from a combination of iron and manganese.
