Diplomite

Diplomite is a term that does not correspond to a widely recognized substance in current scientific literature. In practice, it is sometimes encountered as a misspelling or variant of dolomite, the common carbonate mineral with the formula CaMg(CO3)2, though there is no standard definition for a mineral or compound specifically named "diplomite."

Because the term lacks a stable, widely accepted meaning, its usage is ambiguous and may reflect transcription errors, regional naming variations, or references to fictional materials in literature. When encountered in a text, readers should examine the surrounding context and consider whether the author intended "dolomite" or another term.

Dolomite is a calcium magnesium carbonate mineral that crystallizes in the trigonal crystal system and typically forms rhombohedral crystals. It forms through diagenetic replacement of limestone or by precipitation from magnesium-rich fluids and occurs in sedimentary rocks worldwide. Dolomite crystals are commonly white or gray, sometimes tinted by impurities. It has a Mohs hardness of about 3.5 to 4 and a specific gravity around 2.8 to 2.9. Dolomite is quarried as a decorative stone and is also used as a source of magnesium oxide and as a cement production additive when ground as dolomitic limestone.

Because "diplomite" is not a standard mineral name, there is no established chemical formula or explicit set of properties for it. If you encounter the term, check the citation or context to determine whether it was intended to refer to dolomite or to another material.
