Dark Blue Obsidian SphereGenerally, obsidian in blue form appears as a pale blue rock form that looks very much like glass. It is a silica rich volcanic rock and occurs when viscous lava cools at a very rapid rate. Natural deposits of blue obsidian are currently being mined in certain parts of Greece, as well as in the Atlas Mountains in Morocco. Using this crystal during meditation may greatly help you in attaining levels of transcendence previously unavailable to you.
