Chalcedony is a cryptocrystalline type of silica that is normally white to gray, gray-blue or brown in coloration, but can assume a variety of colors. Fine intergrowths of moganite and quartz minerals make up its composition. Its chemical structure is silicon dioxide. It exhibits a Moh’s scale hardness of 6 to 7, a specific gravity of 2.59-2.61, and is translucent. The blue variety, sometimes referred to as “Mt. Airy blue,” “Mojave,” “African Blue,” or “holly blue,” depending on the locality, can be found in places such as Namibia and the United States. Oregon is the current source of the most valuable blue specimens. Blue chalcedony was used in carvings and jewelry in Greece, Egypt and Rome, and it was also believed to imbue powers to its holders. Native American Indians considered it to be a sacred stone and used it during ceremonial activities to promote stability.

Blue chalcedony is said to stimulate the throat chakra. This makes it an excellent companion crystal for anyone who does public speaking for a living. If you are a political speaker or a lawyer, wearing or touching this stone (particularly to the tip of your tongue) may assist you in coming up with powerful counter arguments. If you are an actor, rubbing it against your throat and lips could enhance your performance. Cicero himself, the famous roman actor, is rumored to have worn blue chalcedony around his neck. Singers should soak it in a cup of water for an hour before their performances and then drink it for maximum effect. Regardless of who you are or what you do for a living or in even in school, blue chalcedony’s presence could possibly ease your stage fright or anxiety toward public speaking. Aside from these benefits, blue chalcedony is believed to have a calming and peaceful influence on its environment and the people within it, as is generally the case with blue crystals. Placed in the home and workplace, it may ease tensions between family members or coworkers that are at odds with one another, fighting for their place at the top of the pecking order. Blue chalcedony could also come in handy during stressful trips, such as business trips or trips where your children must come along. Many use it as a meditation stone, claiming that it encourages reflection and prepares one for action, yet assists in holding back words one might later regret speaking. It is said to instill feelings of generosity and benevolence and promote new ideas, good will and brotherhood.

Crystal healers use blue chalcedony to treat ailments of the throat, such as inflammation and chronic hoarseness. It is also said to reduce the occurrence of sleepwalking, soothe chilblains, encourage the flow of body fluids and reduce edema, ease glaucoma, stimulate milk production in lactating mothers, and alleviate respiratory problems such as hay fever and plant allergies. It may also prove beneficial in the treatment of dementia, gallstones, childhood illness, obsessive compulsive and bipolar disorders, and Tourette’s syndrome. Some claim that blue chalcedony’s influence seems to ease the symptoms associated with autism and Asperger’s disease.
