Chalcedony is a type of cryptocrystalline or microcrystalline form of silica, composed of very fine intergrowths of quartz and moganite. It can occur in a wide range of different colors, sizes, and shapes. It is commonly found in the United States, Brazil, Turkey, Australia, and parts of Africa. It often has a waxy luster and may be semitransparent or translucent. Varieties of chalcedony include agate, jasper, carnelian, onyx, and chrysoprase.
From a metaphysical perspective, chalcedony is considered a nurturing stone that promotes goodwill and enhances group stability. It can be used to assist in thought transmission and telepathy. This peaceful stone absorbs negative energy and brings the mind, body, emotions, and spirit into harmony.
Chalcedony is connected to the throat and third eye chakras. When placed on the throat, it encourages reflection and careful decision-making, promoting positive communication. It also stimulates the third eye chakra, opening the mind to new ideas and promoting a broad-minded perspective.
In terms of emotional energy, chalcedony helps to alleviate hostility and transform melancholy into joy. It eases self-doubt and encourages optimism. It's often used in crystal healing for its properties related to memory improvement, easing the effects of dementia and senility, and increasing physical energy.
The stone is also known to foster maternal instinct and is considered a good stone for pregnancy and lactation. It's seen as beneficial in treating psychosomatic diseases, improving mineral assimilation, and combating mineral buildup in veins.
