Only about 2% of the diamonds that meet physical criteria carry the unique energies that can be used therapeutically.
They are also known as 7-color-ray Diamonds and Therapy Diamonds, and are sold under the trade name TheraDiamonds™.
Physically, a healing Diamond must have a high clarity and be a round brilliant cut. Energetically, it must carry of spectrum of seven colors in relatively equal amounts. This color is not the same as the “fire” that diamonds can display under certain lighting conditions.
Conflict-free diamonds are those that are sold by legitimate miners who do not use the profits of their sale to fund terrorism, rebel movements, violence, and human rights abuses.
