Aragonite, like calcite, is a form of calcium carbonate, the same mineral that also forms seashells.It is the material that makes up sea shells. In nature, this mineral gets recycled back and forth between living and nonliving forms. If you keep an aquarium, a piece of aragonite will help create a natural, healthy environment for the living creatures inside. You wouldn’t want to use the pretty pieces for this, though, since aragonite will gradually dissolve in water.
Like calcite, aragonite comes in an amazing variety of formations and colors. We often see it in three main color patterns:
The white piece is a type of stalactite sometimes called “cave calcite.” These rarer forms of aragonite appear as clusters of colorless spikes or needles.
The little brown-sugar-colored cluster is called a “Sputnik” aragonite (no one seems to know why, except that the name sounds cute, and the formation looks vaguely like a wee space ship). They are especially popular, maybe because they give off such a friendly vibe — sort of like a little mineral pet. There is also a banded brown/golden/white variety, which sometimes appears striped
Blue aragonite has a very distinctive color, an eye-catching robin’s egg blue, and this piece has a really cool pick-up-sticks, coral-like mass formation as well.
This abundant mineral is found all over the world. It’s great for grounding, and even for grounding other crystals.
Care and caution: Some forms of aragonite may contain lead or other dangerous elements, so do not use aragonite to make crystal elixirs.
