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 a full 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.
