Chalcedony History

The first recorded discovery of chalcedony was reported in Istanbul Province, Turkey. It is theorized the name chalcedony comes from the name of the ancient town Chalcedony in Asia Minor. Today, deposits are found all over the world in Brazil, India, Madagascar, Malawi, Namibia, Zimbabwe, Sri Lanka, Uruguay and California. In its antiquity, chalcedony was commonly used as a wearable accessory with cameo carvings of water and air gods and goddesses. It was also used in the Middle East during the 1st and 2nd century to create seals, knives and other jewelry. Chalcedony still is commonly used in accessories such as rings and necklaces.

Chalcedony Metaphysical Properties

This gemstone is thought by many to be lucky for Cancer signs and a protective stone for Sagittarius. Many people believe in the healing and cleansing properties of the stone that include the absorption and dissipation of negative energy so that it does not transfer to other people. This is likely why chalcedony is also thought to align the body, mind and spirit.

In chakra practices, chalcedony is believed to be the stone of communication and is often placed by the pharynx to stimulate the throat chakra. The throat chakra is considered the voice of the body and allows energy or pressure from the other chakras to be released. If the throat chakra is blocked it is believed to cause problems with other chakras. Specifically, blue chalcedony is favored for this practice.

Chalcedony Geological Properties

Chalcedony is a mix of silica cryptocrystalline and moganite. Moganite has the same chemical composition as quartz but differs in the way its crystals form. Chalcedony is also typically a generalized name to encompass all cryptocrystalline forms of quartz. Cryptocrystalline structures have very fine crystalline structures that are invisible to the naked eye. While comprised of fine layers, the layers are densely compacted resulting in a stone more durable than other forms of quartz. These cryptocrystalline forms of quartz come in a wide variety of patterns, colors and sizes. Examples of chalcedony varieties are blue chalcedony, agate, carnelian, chrysoprase and bloodstone. However, unlike most quartz varieties, chalcedony in its natural state appears waxy or dull. While most quartz typically presents itself in trigonal forms, chalcedony occurs in various nodular and botryoidal patterns.
