C&S-Chalcedony-Genuine

Chalcedony

Softly translucent, the serene hues of Blue and Lavender Chalcedony remind us of a calm sea, or the muted purple shades of dusk. Native Americans used Chalcedony to promote emotional balance and enhance vitality. Today the wistful shades of Chalcedony, either alone or in combination with other pastel-colored gems, attract those looking to escape the daily grind. Not all Quartz gems form as a single crystal, like Amethyst or Citrine. Some form from a number of fine-grained micro crystals. When this is the case, these gems are called “Chalcedony”. Naturally colored, Blue Chalcedony originates from the continent of Africa. Its Lavender cousin hails from the United States, and is also naturally colored. As fashion designers reinvent styles that remind us of the economic boom years of post WWII America, the feminine charm of such apparel becomes enchanting when paired with powdery Chalcedony gems. The softness of their colors complements all skin tones, especially those with cooler complexions.
