Blue Chalcedony is a stone with a delicately feminine aura, a stunning blue gemstone that exudes elegance and a blue hue that evokes the sea and seems calm and lovely. Your Blue Chalcedony Pendant will make you feel at rest every time you gaze at it, much as when a cool wind caresses your face. The birthstone for those born in the month of March is blue chalcedony. One of the most beautiful pieces of jewelry one may own is this subdued Blue Chalcedony Pendant. It features a subtle blue translucence and virtually imperceptible movement inside the stone, which symbolizes reverent silence and calm.
