Origins and Occurrence

Chalcedony is a cryptocrystalline variety of silica, composed primarily of tiny quartz crystals. It is typically found in association with volcanic rocks, often forming nodules, veins, and stalactites. Worldwide, significant deposits of chalcedony can be found in countries such as Brazil, Uruguay, Madagascar, and India.

Properties and Characteristics

Chalcedony exhibits a wide range of colors, including white, gray, blue, green, pink, and yellow. Its translucent to opaque nature allows light to pass through, creating a soft, ethereal glow. Moh’s hardness of 6.5 to 7 makes chalcedony durable enough for use in jewelry and other decorative applications.

Types of Chalcedony

Chalcedony encompasses various subtypes, each with its distinctive appearance and properties:

• Carnelian

  : Known for its vibrant red-orange hue, carnelian is often associated with courage, energy, and creativity.

• Chrysoprase

  : A rare and highly prized variety of chalcedony, chrysoprase owes its vibrant green color to trace amounts of nickel.

Agate deposits are found worldwide, with notable sources in Brazil, Uruguay, Mexico, and India.

Properties and Characteristics

Agate typically exhibits a range of colors and patterns, including white, gray, blue, green, red, and orange. Unlike chalcedony, agate is commonly translucent or opaque and has a Moh’s hardness of 6.5 to 7. The presence of parallel stripes or layers is a defining characteristic of agate.
