The name has already passed on this blog page a few times, time to pay more attention to it. Obsidian is rapidly cooled and cloted Pyroxene, which forms an essential lava species in the construction of the moon.It is found on Earth in Yellowstone in the US and in Scotland and Greece. So there's a good chance your piece of gem doesn't come straight from the moon. It is black, shiny and opaque in colour. For spiritually landscaped planet dwellers it is a very interesting stone, as the deep insight and cleansing stone is that triggers personal growth and clearing of ancient ballast from the past. It can help its wearer to reduce fears, blockages, trauma complications and conditioning-related behaviour, which can then bring to light a lot of intense emotions, especially among the more sensitive residents. Fortunately it also says to contribute to reduction against all kinds of negative spiritual influences. It also relieves pain and stimulates digestion. Note this is about real black obsidian, not the glassy blue variant, which you can find along the North Sea beaches.
The black glass-like rock is used in ancient times to make mirrors, hence the name. Obsis means "vision" translated from Old Greek. It is one of the theories about the origin of the name of the gemstone. It consists mainly of silica and to a much lesser extent aluminium oxide. Because the lava has cooled so quickly it does not contain a cristal system and over time it lapses. It was used for making arrowheads a long time ago because it is very sharp. The Maya used it for their macuahuitl, a wooden sword with obsidian protrusions, first for ritual purposes, but much later also to kill people. In yeasts that were given to a deceased for his journey through the afterlife are also often obsidian. In short, a versatile piece of stone.
