Aragonite – Finest form of calcium carbonate

Aragonite is one of the common carbonates like calcite. Calcite and aragonite have same molecule levels, thus they are called as paramorphs. The only differences in these paramorphs are their internal crystal structure. Aragonite has four sided orthorhombic structure whereas the calcite has six sided hexagonal crystals. Calcite is more common than aragonite because of its presence in the seashells, pearls and fossils. Both calcite and aragonite are formed under low temperature conditions but aragonite has low stability when compared with calcite. Aragonite is one of the wonderful collector minerals in the world due to their larger existence. The mineral forms in different attractive structure such as long- needle like form and in various structures.  Oolitic aragonite is the main source of aragonite. Oolitic aragonites are formed in the marine areas naturally. These egg shaped particles are initially saturated with higher amount of calcium carbonate. Due to solar radiation and pho
