Heliotrope
Heliotrope – natural stone
Heliotrope is a variety of chalcedony, also known as bloodstone or dragon’s blood. The heliotrope mineral is mainly found in nickel-bearing weathering zones of basic rocks. It is found in many places around the world, including Brazil, India, China, South Africa, Australia, Russia and Poland. Its name comes from the Greek words “helios” and “tropos,” meaning “sun” and “turning,” referring to the fact that when heliotrope stones are turned under water, they reflect red. Heliotrope stone has an interesting structure as it is made up of amphibole, tiny quartz crystals and other minerals. These properties make each stone unique, with an incomparable pattern on its surface. Its hardness on the Mohs scale is 6.5-7, while its density is 2.61 g/cm³. Characteristic features of heliotrope include a vitreous luster and a trigonal crystal system.
