Tricolor Elestials are milky white, smoky and Citrine in coloring. It is often difficult or impossible to differentiate quartz arenite from quartzite. Quartz occurs in virtually every color. Wind and water (and ancient glaciers too) are common forces that move crystals from their original location in the seams/pockets they were grown in. Today, billions of quartz crystals are used to make oscillators for watches, clocks, radios, televisions, electronic games, computers, cell phones, electronic meters, and GPS equipment. These manufactured crystals can be grown in shapes, sizes and colors that match the needs of manufacturing processes. The effect results in seemingly a crystal within a crystal and the interior crystal may have a ghostly look, hence the name phantom.
