Aragonite
Aragonite
Aragonite's name is derived from the location of Molina de Aragon, Spain, the province where it was first discovered. Aragonite occurs in Agrigento, Sicily, Italy, in the famous sulfur mines, as well as on Mount Vesuvius, Italy. Aragonite specimens are highly prized by mineral collectors for their wide variety of forms, which include twins and pseudomorphs (uncharacteristic crystal forms). As an added bonus, many specimens are fluorescent as well as phosphorescent, a rare occurrence among minerals.

History
In the Sisk Gemology Reference, Jerry Sisk writes, "Aragonite is a fascinating mineral." In its biogenic form, it is produced by marine mollusks and one of two components within the nacre of pearls. It's also found in coral. Aragonite is a polymorph of calcite, sharing the same chemical formula but with different crystal structures. We like aragonite as a gemstone for collectors, although it is occasionally set in jewelry. Most cuttable, or facetable aragonite is colorless or nearly so. The full color range of aragonite includes white, yellow, brown, green, gray, blue, violet, and red. This versatile stone has a color to please every collector. Although the crystals can be attractively displayed in necklaces, we don't recommend it for rings and bracelets. Aragonite is ideally suited to add variety to a collector's treasure trove.
