These single points can range from 1/4″ high to 20-feet-long, or more! High quality crystals are glossy, and look great once the dirt and iron are removed from their surfaces/facets. Other clear crystals have crusty mineral deposits on them that do not wash off. In Brazil and Madagascar, these single points are first polished down to the clear zones. Then the bottom is cut flat and polished so the crystal will stand up vertically. I call these “crystal towers” or lighthouses. They resemble Egyptian obelisks, which have 4 flat sides and a tiny pyramid at the tip. The crystal towers have 6 sides, with a six-sided pyramid at the point. These are elegant shapes for display on tables and altars. The vertical presentation helps connect the energies of Heaven and Earth.
