The name chalcedony comes from the Latin word ‘chalcedonius’, a term used for a translucent kind of jasper, and is actually a type of quartz mineral that comes in many forms and colors, including agate, carnelian and onyx, to name a few. Blue chalcedony, usually translucent and ethereal in quality, is most popular in jewelry. It is revered for the effortless way it reflects and moves with light, much like water. Chalcedony in its raw form has a waxy luster but can be polished to a high gloss, and may be semi-transparent to translucent. It also can be found in a variety of blue colors, ranging from light transparent blue to a solid baby or sky blue.
It is recorded in and reflected in many a history account dating back to the Greeks that Chalcedony brings the wearer a sense of steadiness and calm, helping to avoid impulsivity. It is the stone of self-reflection, and you could imagine gazing into its cloudy depths to gain a better understanding of yourself.
