Obelisks were common in Ancient Egypt, and usually took the form of a tapering column with a pyramid on the top. They generally represented the sun god Ra, and flanked the entrances to temples and important buildings in pairs. Lehrer Cosmic Obelisk designs are long six-sided Quartz crystals, with laminated colored gemstones at the top of them. The facets at the top and bottom of the design are cut at a very precise angle so they display the hue from the colored stones. To the observer, the color appears to have jumped up and down the length of the Quartz and is being transmitted outwards.
