An Obelisk is often representative of a Sacred Stone, a marker outlining a particular area.  It is a strong emphatic, directional shape represents the connectivity between the earth and the sky or sun.  Obelisk date back to the Egyptians. They amplify energy and focus it out through the apex, or top of the point. Great to use in meditations directing energy in and out of the body, as well as ornamenting the home or office.
