THERAPEUTIC QUALITY
Color, brightness, and clarity are of equal importance in therapeutic-quality Emerald. The color green that most closely matches the green of the rainbow is most powerful. Therapeutic Emerald is a rich, radiant, pure bright green with good clarity. When the necklace is examined as a whole, it should either be free of black flecks or have only a minimal number of them.
Avoid any Emerald that is cloudy or dull in appearance or noticeably yellow-green or blue-green in color. This is not therapeutic Emerald. The blue in particular is a contaminant that can alter the vibration of Emerald. Not only is it not therapeutic, but it can actually have a harmful effect.
