Diamantissa

Diamantissa is a term that appears in a small number of works and discussions but does not have a single, widely accepted definition in major reference sources. The word seems to be a coined form built from "diamond" with a suffix that suggests a trait or category, implying some diamond-related quality. Because there is no standardized usage, the meaning of diamantissa varies by author and field.

In speculative fiction or worldbuilding contexts, diamantissa may denote a material, object, or property characterized by exceptional hardness, brilliance, or refractive qualities reminiscent of diamond. In mathematical or geometric writing, diamantissa has sometimes been used as a provisional name for a construct inspired by diamond-shaped forms or tilings, or as a playful label for a metric or invariant defined within a particular paper. These uses are idiosyncratic and not part of formal nomenclature.

In linguistics or semiotics, the term might appear in glossaries to describe a metaphorical attribute associated with diamonds, such as clarity or value, again in a nonstandard way. When encountering diamantissa in a text, readers should consult the author’s definition or the surrounding context to determine what is meant. The term is not standardized, and there are no canonical references.
