Red Jasper is an opaque, microcrystalline variety of Quartz with large, grainy crystals and is a member of the Chalcedony mineral class. It occurs in nodules or as fillings in fissures and may be found the world over. Its vibrant red to terracotta-red-brown is due to high iron content and may contain other minerals or impurities that create rich patterns. Red Jasper is a major component in Brecciated Jasper, Poppy Jasper and Rose-eye Jasper, and is prominent in many area specific Jaspers, such as Cherry Creek Jasper and Mookaite Jasper. It is believed Red Jasper was likely the “Ruby” listed in the Bible – the Odem, or first stone in the breastplate of Aaron, the High Priest, engraved with the tribal name of Reuben. Red is a color that represents passion, energy, and life.
