How do you identify blue aragonite?

Although Aragonite crystallizes in the orthorhombic system, most prismatic crystals are hexagonally shaped due to the twinning. Trillings can be identified by their multi-directional basal striations from each individual member crystal.

What is aragonite slurry?

Aragonite is a pure form of calcium carbonate (CaCO3) which is competitive with U.S. domestic limestone. The aragonite is then moved by yard belt to single wing stackers, which deposit it over a live tunnel feeding onto a ship-loading belt. The material is loaded into ships at a rate of 3,400 tons per hour.

What is pink aragonite good for?

Mental: Pink Aragonite brings gifts of tolerance, patience and flexibility.

Why does aragonite dissolve?

Organisms such as corals, clams, oysters, and some plankton use carbonate ions to create their shells and skeletons. When aragonite saturation state falls below 3, these organisms become stressed, and when saturation state is less than 1, shells and other aragonite structures begin to dissolve.

What do aragonite crystals look like?

They are snow-white, twisting, curving, slender fingers of calcium carbonate aragonite. Large specimens of this oddly formed aragonite show no crystal faces but present in attractive twisted forms. A number of very well-known mines have been a source of these unusual looking but fascinating aragonites.
