Quartz is a mineral in a broad sense with similar chemical composition. Quartz can be divided into two main subsets. Crystalline (macro-crystalline), the variety is generally associated with quartz. This group includes Quartz, Amethyst, Smoky Quartz and others. The second group are polycrystalline (micro-crystalline), and have in turn several subgroups.Here we find the groups Chalcedony, Jasper, Quartzites and silicate replacements. This group also includes Petrified Wood or fossile tree where the organic material in time have been replaced by quartz material but with preserved structures and pattern.

Fossils as gems in healing (Source: ChatGPT)
Fossils, used as gemstones in crystal therapy and healing, are attributed unique properties based on their connection to Earth's history and their organic origins. They are not a traditional gemstone but consist of the mineralized remains of plants or animals, such as fossilized corals, shells or trees (eg petrified wood).
