Chalcedony Meaning, Powers and History

chalcedony-agate-facts-history.webp Chalcedony is brittle and has a waxy, dull luster. It may be semitransparent or translucent and is vitreous when polished. It can assume a wide range of colors, but those most commonly seen are white to gray, grayish-blue or a shade of brown ranging from pale to nearly black. When chalcedony comes in different colors, the colors are due to embedded minerals. Chalcedony is not its own mineral species- it is a form of quartz iconquartz in microcrystalline form. Other forms- with multicolored bands for example Agate, have their own name. Chalcedony rates a 6.5 - 7 on Moh's hardness scale.

chalcedony-petrified-wood-facts.webp Chalcedony can be found as vein fillings or crusts in volcanic rocks, as the main constituent in silica-rich marine sedimentary rocks, as layers in limestone and marls, as cement in sandstones, and as a fossilizing material. A well-known example of Chalcedony forming pseudomorphs after organic material is in the Petrified Forest National Monument in Arizona- there; an entire forest transformed into petrified wood. Remains of this forest are now found in large silicified logs in the area. Another example is in coral. In Tampa Bay, Florida, coral has been chemically replaced by Chalcedony and its original form is preserved. Tiger's Eye is yet another example- the golden streaks within the stone are caused by Crocidolite, a fibrous mineral that was chemically replaced into Chalcedony through pseudomorphism.

chalcedony-emotional-physical-facts.webp Chalcedony has many healing properties. It is a nurturing stone that promotes overall generosity. It is said to aid with emotional balance, stamina, vitality, endurance, energy, kindness, and friendliness. It alleviates hostility, self-doubt, negative thoughts and emotions, and nightmares. Chalcedony is said to help symptoms of dementia and senility. The stone has also been said to have the power to heal the eyes, gallbladder, bones, spleen, and blood and circulatory systems.
