Where does Aragonite come from?

Aragonite Placeholder

Aragonite is found in small deposits around the world.  Some of the more notable deposits are in Australia, Austria, China, Czech Republic, France, Germany, Greece, Hungary, Italy, Mexico, Morocco, Namibia, Peru, Portugal, Romania, Slovakia. Spain, United Kingdom, and the United States (Colorado, New Mexico, Pennsylvania, and South Dakota).

What is Aragonite?

Aragonite is a carbonate mineral. Carbonates are an important part of the Earth’s crust and are found in sedimentary, metamorphic, and igneous rocks. Carbonates are minerals which contain the carbonate group CO3 as their basic structural unit. They form in a trigonal system with one carbon atom centrally located between 3 oxygen atoms. While there are over 70 types of carbonate minerals, the most common are Dolomite, Siderite, and Calcite. Aragonite is a relatively rare stone which is chemically identical to Calcite, the only difference is the structure on a microscope level. Aragonite’s crystal system is orthorhomic, while Calcite’s crystal system is trigonal.  Aragonite can be colorless, as well as brown, yellow, grey, red, green, or blue.

How is Aragonite created?

Aragonite is chemically identical to Calcite, but is formed under different geological conditions. It is found in the oxidized zone of ore deposits, in caves as stalactites, near hot springs, and in mineral veins. It is also produced in mollusks and corals by biological processes that have yet to be fully understood.

How is Aragonite mined?

Aragonite is the principal mineral mined in multiple locations. Among other uses, it is used to make cement and soil neutralizers, and to help maintain the pH balance in salt-water aquariums.

Aragonite Associates

Aragonite is associated with Calcite, Celestine, Malachite, Smithsonite and Sulfur.

Is Aragonite natural?

All Aragonite is fully natural, enhanced only by cutting and polishing.
