aragonite, widespread mineral, the stable form of calcium carbonate (CaCO 3) at high pressures. It may be distinguished from calcite, the commoner form of calcium carbonate, by its greater hardness and specific gravity. Aragonite is always found in deposits formed at low temperatures near the surface of the Earth, as in caves as stalactites, in ...

Aragonite was established in the early 1900s as a mining site for the mineral aragonite, used as a decorative stone in building. The site was abandoned after a few years. When first opened, the site would have been very remote, which I believe is why the buildings were built in that area to support the miners. The mine was reopened (not the ...

A really stunning piece from the Hull Mine, in Arizona. Red calcite, blue fluorite, green willemite, and potentially white aragonite--though the latter is not known for certain. Note, the willemite is nicely phosphorescent, while the alleged aragonite, is not. Shown in SW+LW, SW, LW, and natural both A-side and B-side.

Description. Aragonite is a carbonate mineral, one of the two common, naturally occurring polymorphs of calcium carbonate, CaCO3. The other polymorph is the mineral calcite. Aragonite's crystal lattice differs from that of calcite, resulting in a different crystal shape, an orthorhombic system with acicular crystals.

From archaeological investigations in the cave, we know that several of the aragonite formations were quarried by prehistoric people. We also know, based on examination of curated collections, that some artifacts recovered from prehistoric archaeological sites in eastern North America are made from materials similar to the Wyandotte Cave ...

There's this cool thing called the Mohs scale, and it's like a ruler for mineral hardness. It goes from 1 (super soft) all the way up to 10 (super hard). Both blue aragonite and Caribbean calcite fall near the bottom of this scale. Blue aragonite is around 3.5 to 4, while Caribbean calcite is close by at 3 to 3.5.
