Colorless brown crystallized aragonite.
Aragonite or aragonite is one of the crystalline forms of calcium carbonate, along with calcite and vaterite. It can be found in the form of stalactites, and also in the shell of almost all mollusks and in the skeleton of corals.
Aragonite is usually only used as an ornamental or collector's stone.
The mineral includes a label with the name and origin and is attached to a cardboard box. 4 cm square.
*The price is per unit (a single cardboard box of the four shown in the photo)
Since the minerals are natural, you will receive a piece similar to the one in the photograph. The minerals come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
