Mystically Serene and Cool Chalcedony

Chalcedony is a form of silica, composed of very fine crystalline filaments of the minerals quartz and moganite. Silicon Dioxide is Chalcedony’s natural structure and form. It can appear in colors white to grey, greyish-blue, or brown- ranging from very pale to nearly jet black. Chalcedony has a unique luster, and may be semitransparent or translucent.

“The term chalcedony is derived from the name of the ancient Greek town Chalkedon in Asia Minor, in modern English usually spelled Chalcedon, today the Kadıköy district of Istanbul. At least three varieties of chalcedony were used in the Jewish High Priest’s Breastplate. (Moses’ brother Aaron wore the Breastplate, with inscribed gems representing the twelve tribes of Israel). The Breastplate included jasper, chrysoprase and sardonyx, and there is some debate as to whether other agates were also used.” (Excepted from Wikipedia)

Chalcedony promotes a strong sense of brotherhood and good will, used by many Native Americans for this purpose as well as sight in meditation. It brings the mind, body, emotions and spirit into harmony. Chalcedony instills feelings of benevolence and generosity, alleviating hostility and transforms melancholy into joy. Absorbs and dissipates negative thoughts, emotions and bad dreams. Perfect for magnifying its crystal energy in grids or use when charging crystal elixirs to soothe and restore balance, from the conscious busy mind to the sweet inner child. It is an excellent assistant for those who are worry laden people, by encouraging life in the present instead of manifesting and projecting into an imaginary future.

Chalcedony is known as the Speaker’s Stone, the stone of one who must measure his words. It encourages reflection and meditation, its gentle radiance preparing us for action but helping to hold back words we might regret. Blue Chalcedony is specific to the throat chakra and is excellent for public speakers, life coaches, psychologists and those who speak for a living. Actors or performers might rub it against their throat, while singers may drink a glass of water in which rutilated Chalcedony has soaked for an hour before going on stage. Wearing this crystal around the solar plexus can help overcome self doubt or stage fright while wearing it around the neck helps the fear of public speaking.

Chalcedony is most useful for treating chronic hoarseness and inflammation of the throat. Chalcedony also improves mineral assimilation and combats mineral buildup in veins. It increases physical energy and has been well known to help heal the eyes for centuries, and assist gallbladder, bones, spleen, blood and circulatory system. Blue Chalcedony helps an afflicted person’s over sensitivity (such as fibromyalgia and glaucoma) caused by weather changes or pressure, and stimulates milk production in nursing mothers. It helps alleviate plant allergies, hay fever, and other respiratory problems, aids in their treatment and helps lessen the effects of Alzheimer’s and dementia, childhood illnesses, gallstones and inflammation, and may soothe the symptoms of autism and Asperger’s disease, Tourette’s syndrome, bi-polar and obsessive compulsive disorders.
