Rich in symbolism and easy to recognize, chalcedony is a pastel-blue stone. It is believed to offer many benefits to its wearer and remains highly sought after today.
In jewelry, one of chalcedony's many advantages is its versatility. It pairs with all kinds of metals, including yellow gold, white gold and silver. Its blue-gray color looks especially beautiful with white-toned precious metals, such as silver and white gold.
Sometimes called chalcedonite, chalcedony takes its name from the city of Chalcedon (or Khalkedon) in Asia Minor (Turkey). Since its discovery, different civilizations have used the stone in many ways. For thousands of years, it was a favorite stone in many cultures. During the Neolithic era, chalcedony was used to make tools. In ancient times, the Egyptians used it to make figurines and amulets. In the Middle Ages and Renaissance, it was a favored stone for sculptures and ornaments. The Bible also mentions chalcedony in the foundations of Jerusalem's city wall.
Chalcedony is a gemstone long considered sacred by Native American tribes, who used it in traditional ceremonies. It remains rich in symbolism today, representing serenity, calm and balance for its wearer.
As noted earlier, chalcedony has had many uses throughout history. Today, it is especially valued in jewelry and the decorative arts, particularly for its soft color. It is a popular choice for ornamental figures and sculptures, including cameos.
Chalcedony most often forms in sedimentary and volcanic environments. When magma reaches the surface, the stone can form in cavities created by gases as the magma solidifies. The main countries where chalcedony is mined are the United States, Brazil, India, Madagascar, Zimbabwe, Namibia, Myanmar, Mexico and Uruguay.
Chalcedony is a cryptocrystalline variety of quartz composed of silicon dioxide (SiO2). Its crystals are so small that they are extremely difficult to see, even under a microscope. This gemstone has a rhombohedral crystal structure and includes many familiar varieties, such as onyx, agate, green chrysoprase, red carnelian, red jasper and brown sard. Chalcedony is a relatively fragile stone, with a hardness of 6.5 to 7 on the Mohs scale and a density of 2.5 to 2.6.
Broadly speaking, chalcedony can refer to any translucent, uniformly colored cryptocrystalline quartz. In the gemstone trade, however, the name is used for stones ranging from milky white to blue-gray, sometimes with a hint of mauve. Chalcedony also occurs in shades of light brown and yellow. Its color comes from impurities, generally iron, nickel, copper or titanium. Chalcedony is usually cut into cabochons to bring out its luster. It is also available in oval, round and cushion shapes.
Chalcedony is believed to offer its wearer many benefits for both mind and body.
Emotionally, chalcedony is considered an especially gentle, positive and soothing stone that brings harmony and balance. Believed to ease anxiety, grief and anger, it is often recommended for people who are anxious or easily irritated. It is also said to encourage self-confidence and make speaking and expressing yourself easier, making it an ideal companion for shy people. It is also believed to stimulate creativity and self-expression.
Chalcedony is also said to offer physical benefits. It is believed to soothe throat infections, particularly in the larynx, and help with speech difficulties such as stuttering. It is also said to help regulate hormonal issues, especially those related to menopause, and stimulate lactation in breastfeeding women.
Chalcedony is a fairly fragile gemstone that needs careful handling. It is sensitive to bright light and high heat, so avoid prolonged exposure. Be sure to remove your jewelry when handling household cleaning chemicals, for example.
To clean it, use lukewarm water and dish soap. Rinse with clean water, then dry the stone with a soft cloth.
