Chalcedony comes in many forms depending on the minerals present during formation, but few can compare to the bright colors of chrysocolla chalcedony. Sourced from Asia and the Americas, chrysocolla chalcedony has become a prized gemstone in recent years.

The chrysocolla inclusions make this unique mineral a shocking blue color. This pigment comes from oxidized copper, an important part of the stone's chemical makeup. Chalcedony is a form of silicate with a cryptocrystalline structure, meaning its crystals are only revealed under microscopic observation. It forms in a variety of environments, both in acidic and basic volcanic materials and in sedimentary environments near the Earth’s surface. This special chrysocolla chalcedony, however, forms primarily in Southeast Asia.

These chrysocolla chalcedony gemstones are each shipped in a sturdy carton, along with a certificate of authenticity.

Every specimen is a unique gemstone formation and all have been photographed and listed individually by size. See all available specimens in the collection below!

Chrysocolla chalcedony is a prized form of chalcedony, owing to its striking turquoise coloring. Sourced primarily from Indonesia, the United States, and Taiwan, the material also appears in Central America, South America, and Spain. The ratio of chrysocolla to chalcedony in different sources produces different intensities of color and translucence. 

Chrysocolla is a beautiful mineral dominated by silicon and copper which forms during copper sulfide mineralization. The oxidation of its copper component gives the mineral its unique blue coloration and is mainly found in copper deposits formed from volcanic activity.

Combined with a chalcedony quartz base, chrysocolla chalcedony is a rare and sought-after gemstone. Its popularity has even led to new studies investigating the gemstone. 

The mineral has been used in jewelry for thousands of years, once used by the Romans to weld gold pieces together. This is where it gets its name: khrusós (gold) and kolla (glue)
