Obsidian points of black Obsidian 40-50 mm.

Obsidians are heliocentric. This means that they both absorb and reflect light, which makes them extra healing. If you look through the stone in natural sunlight, this is clearly visible. This helps raise your level of consciousness and promotes your spiritual growth. The Andara obsidian is one of the stones within the gemstone family with the greatest healing effect. It can be used for all possible healings and also helps to raise your consciousness and the accessibility to other dimensions. The Andara Obsidians come in different energetic vibrations and colors; From light to dark, clear to champagne, silver, blue, amber and the rarest of them all, green, yellow, pink and lavender. All stones are ideally suited for meditation and even make it easier to get into a good deep meditation. The Andara Obsidians are known to have also been used by Shamans and High Priests in the past. Obsidian is a naturally occurring volcanic glass. The name is derived from a Roman called Obsius, who is said to have found an obsidian-like stone in Ethiopia in ancient times. Obsidian is formed by rapid cooling of lava with a maximum water content of 3-4 %. If the content of volatile components (water, carbon dioxide) is higher, pumice is formed, because the released gases act as a blowing agent. The formation of volcanic glass is highly dependent on the viscosity of the liquid lava and this in turn is strongly determined by the silicic acid content. The higher this level, the slower the liquid flows. Most obsidians have a silicic acid content of 70% or more and are therefore classed as rhyolites. Less commonly, trachitic, andesitic and phonolithic obsidians are also found that have a lower silicic acid content. The color of obsidian varies quite widely depending on the contaminants it contains. The color is mostly dark green to deep black, although granite with a similar composition is a light colored material. This is usually caused by particularly finely divided hematite or magnetite. Snowflake obsidian contains inclusions of spherically grown structures, most of feldspar or cristobalite, called spherulites. They arise from spherical crystal growth from a single central growth core. Obsidian is a metastable material that reverts to its crystalline, more stable form over time. Volcanic glass is therefore not known from the Paleozoic and Precambrian. In the Stone Age, obsidian was a coveted raw material because it forms razor-sharp cutting edges. It was used for knives and weapons. Today it is a popular material for art objects and is also used as a semi-precious stone in jewelry. It is then cut as if it were a crystal.
