The indigo glow seen when you hold our highest quality Sodalight to a light source comes from the unusually high presence of crystalline Indigo in our gems. Most commercially available Sodalight is opaque and dyed to hide its white streaks, rendering it nontherapeutic. Our non-dyed, deep-blue gems provide Sodalight’s benefits and a gentle dose of indigo color ray. Therapeutic Quality Sodalight Therapeutic quality Sodalight spheres are a deep, rich blue, with relatively consistent color throughout the entire sphere. When the highest-quality Sodalight is first fashioned into spheres, it has only a faint suggestion of white streaks or clouds. If more than 10 percent of the sphere’s surface is white, its therapeutic effectiveness is diminished. Therapeutic Sodalight may also have tiny—sometimes microscopic—pinpoints of various other colors, such as black, gold, orange, and silver. Sodalight's nature is to purify the human aura and body by absorbing energies that do not fit its wearer’s overall vibratory picture. A moderate amount of these additional colors, or elements, allows the Sodalight to respond to a wider spectrum of these energies. However, if these colors cover more than five percent of the sphere’s surface, the sphere will lack the ideal proportion of essential and nonessential Sodalight components, rendering it non-therapeutic. The highest quality Sodalight may display its crystalline nature as reflective facets of dark blue or black. If the Sodalight is somewhat translucent, the facets may appear to be contained inside the sphere. Therapeutic Sodalight should not be so transparent or gem-like as to encroach on the properties of Indigo. Sodalight is yet another gemstone that is commonly dyed. Dye hides any white streaks or clouds and prevents the Sodalight from expressing its healing energy. It also clogs the stone’s pores and thus inhibits its ability to absorb disharmony. Consequently, Sodalight that contains any dye is non-therapeutic.
