Diameetrit

Diameetrit is a name that appears in a few regional or historical mineralogical texts, but it is not a widely recognized mineral species in contemporary mineralogy. It is not listed as an official mineral by the International Mineralogical Association (IMA) and is not consistently represented in major mineral databases. As a result, there is no universally accepted chemical formula, crystal structure, or standard set of physical properties associated with the term.

In usage, diameetrit has often been applied descriptively or provisionally, rather than as a formal mineral designation. Some references have used it as a locality label, a tentative name for a poorly characterized specimen, or a miscaptioned entry that corresponds to another known mineral. Because the term has varied meanings across sources, its identity can be unclear and potentially overlap with other minerals or rock materials in different contexts.

Due to the lack of a standardized definition, any discussion of diameetrit should point to specific primary sources to determine what the author intended. Researchers encountering the term are advised to verify through the cited locality, associated minerals, or a formal description, and to check for updates in mineralogical nomenclature. Until a definitive, peer-reviewed description is established, diameetrit remains an ambiguous or provisional label rather than a validated mineral species.
