Chalcedony Properties

Chalcedony is the opaque to translucent form of quartz, otherwise described as cryptocrystalline quartz. A hard mineral, the chalcedony stone occurs in various colors and varieties, and includes gemstones that are popular in their own right, namely, onyx, carnelian, sardonyx, chrysoprase, agate, bloodstone, jasper and aventurine. In the gem trade, however, the name chalcedony is used to refer to varieties of the mineral beside its well-known species. Hence, “chalcedony” usually refers to either the white or blue chalcedony.

Chalcedony Meaning

Since antiquity, chalcedony is thought to dispel bad dreams. More than just a protection against nightmares, a chalcedony stone is believed to repel any negative vibrations, and absorb only positive energy, making chalcedony a stone of virtue. The chalcedony gemstone is imbued with the ability to stave off melancholy, drive away evil, and protect people on their journey: a set of metaphysical properties similar to that of moonstone. Both white in color, chalcedony and moonstone are associated with the moon goddess Diana.

Likewise, both chalcedony and moonstone are birthstones of the zodiac sign Cancer, whose ruling planet is the moon. Cancerians are emotional people who are well-meant, yet get a fair share of negativity, and tend to worry a lot. A chalcedony crystal benefits a Cancer person by chasing away his nightmares and negative thoughts, thereby making him feel more secure and optimistic.
