Aragonite for Sale

Aragonite Quick Notes

The unique thing about aragonite is that it shares a chemical composition but has different crystal structures. If it’s free of any impurities, then it will be white; however, if impurities exist, then the colors can greatly range from a brown to red-orange. Other colors are present as well, which can include yellow, green, blue and pink. The cool thing is that if aragonite didn’t exist, we would see many of our Earth’s organisms since most invertebrate organisms use this mineral as a way to contract their shells.

There are two varieties to be aware of: banded aragonite and cave calcite. A banded aragonite will consists of layers, hence the name. It’s often layered with impure aragonite as well as another mineral, usually calcite. Other minerals may include azurite, gypsum, or quartz, to name a few. If a banded aragonite is polished, it can create a very attractive pattern. A cave calcite, on the other hand, forms stalactites and stalagmites, which are found in cave environments. This can resemble that of a popcorn-like structure.

Since there are so many combinations, aragonite can be so unique, and it’s the main reason why mineral collectors often have it in their collection.

Where is aragonite found?

Most of your aragonite will be found in Spain, however, where you find aragonite will depend on the specimen. Flos ferri specimens, for example, are found throughout Europe, such as England and Austria. Larger pieces, often sky blue in color, can be found in hot spring areas in China. Your red-orange pieces as well as cave calcite are usually mined in southwest United States and Peru.
