Diamond is a crystal of pure carbon with a hardness of 10— the hardest of all substances. Its crystal symmetry is cubic, and Diamond crystals are found in a variety of forms, including octahedrons, triangles, cubes and amorphous shapes. Diamonds are commonly thought of as colorless stones, exhibiting brilliant inner fire when faceted into gems. However, Diamonds are found in many colors— yellow, brown, blue, pink, green, orange and even red. Although Diamonds are highly stable under most conditions, heating them to very high temperatures where oxygen is present can cause them to vanish, transforming into carbon dioxide gas. This is how it is possible to ‘drill’ holes in diamonds using laser beams. Diamonds have long been valued for their magical properties, and Hindus over fifteen centuries ago believed the stones provided their owners with protection from evil spirits, fire, poison, snakes, illness and various dangers. In other cultures, Diamonds were believed to provide victory, courage, faithfulness, purity and enhancement of love.
Long held in the treasuries of kings and queens, Diamonds were believed to offer access to Divine energies. This is one reason why Diamonds are set in crowns. Putting such a stone near the brain, particularly at the forehead, can enhance one’s inner vision and intuitive connection with the higher domains of spirit. Since kings and queens were often viewed as intermediaries between the human and divine worlds, they needed such crowns, which served rather like antennae for attuning to the Divine channels of information and authority. The fact that most royalty has passed away, with access to the Divine realms a fading memory does not detract from the powers one may still access through the proper use of Diamonds. Diamond can assist one in activating the prefrontal lobes of the brain, the seat of most paranormal abilities and visionary consciousness. In fact, in our times, in which the outer kings and queens have been lost, Diamond is a tool one can use to evoke the inner king and/ or queen, those archetypal beings within the self that convey power, knowledge and sovereignty. When spiritual insight is combined with the wisdom of the inner king/ queen, the result is clairvoyance (clear-seeing) and a sense of calm certainty about one’s desires and proper course of action. Diamond crystals are transducers which can make the high-frequency vibrational energies of the spirit realms more available to the conscious self. They can accelerate one’s evolution and open the doors to psychic powers as well.
Worn in everyday life, they can intensify one’s ability to focus consciousness on manifesting one’s goals and dreams. Intensity is a key word for Diamond. They seem to emanate more energy for their size than any other stone. This intensity can work on the emotional body to amplify the power of any emotional state, from bliss to despair. For this reason, one should be vigilant about wearing Diamonds and should probably remove them if one is in a bad frame of mind. However, they can be used therapeutically to intensify and ‘burn through’ underlying emotional issues. For metaphysical use, Diamond crystals are preferable to cut Diamonds because the natural shape acts to strengthen and harmonize the energies moving through them. Diamond crystals can be worn anywhere on the body and will affect the entire energy system and auric field.
