Chalcedony is a cryptocrystalline form of silica, very similar to quartz it also has the make up of Silicon Dioxide - however its structure is different as it is composed of very fine intergrowths of quartz and recently discovered moganite. So it is a mix of trigonal crystal structure of quart, while moganite is monoclinic. Energetically, Chalcedony is thought to soften the energetic body in times of high stress, restoring a state of balance & calmness. When it is blue in color it is said to connect to the throat and third eye, helping to facilitate communication both orally and telepathically. Also known as the stone of brother hood as it is said to bring harmony to relationships with others, sealing up energetic leaks & imbalances.
