Amintite

Amintite is a term that has appeared in speculative geology and various fictional works to refer to a mineral-like substance. It is not currently recognized as a mineral species by the International Mineralogical Association (IMA) and is not listed in major mineral databases such as Mindat, Webmineral, or the USGS Mineral Resources Data System. Consequently, there is no formally accepted chemical composition, crystal structure, or set of physical properties for amintite.

Because it is not formally defined, references to amintite lack a standardized description. Any properties described in sources that mention amintite are unofficial and inconsistent across works. As a result, there is no consensus on its hardness, crystal system, optical properties, or formation.

In fiction and worldbuilding contexts, amintite is often described as a mint-green crystal or alloy-like material with various imagined properties, including energy storage or magical significance. Such depictions are narrative devices rather than scientifically validated characteristics, and they vary widely from one source to another.

Etymology for the name is typically linked to the color or imagery of mint in some depictions, but there is no official or widely accepted etymology associated with a real mineral. Because amintite is not an established mineral, readers should consult fictional or speculative sources for any particular description.
