Aragonite cluster Keychain Key Ring
Aragonite is a calcium carbonate mineral that is typically found in the form of stalactites, stalagmites, and other cave formations. It is also commonly found in the shells of mollusks and in coral reefs.
The chemical formula for aragonite is CaCO3, and it belongs to the same family of minerals as calcite, which has the same chemical formula but a different crystal structure. Both aragonite and calcite are polymorphs, meaning they have the same chemical makeup but different physical properties.
One of the most notable physical properties of aragonite is its relative softness, with a Mohs hardness of only 3.5 to 4. This makes it susceptible to scratching and damage, and it is not typically used as a gemstone. However, it is still valued for its beauty and is often used in jewelry and decorative objects.
Aragonite is also known for its unique crystal structure, which is characterized by long, thin, and spiral-shaped crystals. These crystals can grow to be quite large and are often found in clusters or aggregates. The color of aragonite can range from white to gray, yellow, brown, or even blue or green.
One of the most common sources of aragonite is in caves, where it forms as a result of the dripping of water containing dissolved calcium carbonate. Over time, the water evaporates, leaving behind deposits of aragonite. Aragonite can also form in the shells of mollusks as they grow, as well as in coral reefs, where it is an important component of the calcium carbonate skeletons of coral polyps.
In addition to its use in jewelry and decorative objects, aragonite has a number of practical applications. It is used as a raw material in the production of cement, lime, and glass, and it is also used as a soil amendment to increase the pH of acidic soil.
Overall, aragonite is a unique and interesting mineral that is found in a variety of settings around the world. Its beauty and versatility make it an important resource in a number of industries, from jewelry to construction.
