CaCO3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ca2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ca–O bond distances ranging from 2.43–2.69 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.29 Å) and two longer (1.30 Å) C–O bond length.

Gemstone Information - Aragonite Meaning and …

Aragonite is a carbonated metamorphous gemstone naturally found in stalactites or around natural hot springs. This form of aragonite is often called floss ferri ("iron flowers"), due to its thin, entwined branch-like crystal formations. Another source of aragonite can be found in the mother-of-pearl lining of mollusk shells.

Aragonito - Wikipedia, la enciclopedia libre

Aragonite is unstable in the subsurface, where it reverts to the hexagonal isomorph calcite. This polymorphic reaction causes an 8% increase in bulk volume, which results in a loss of porosity. Coupled with compaction, this porosity loss means that most ancient lime mudstones are hard, tight, and splintery rocks.
