History & usage: The character depicts the White Concave-Sided Diamond. The name includes shape tokens and a color or form descriptor, signaling a geometric diamond shape with a concave edge. Such tokens convey generic cues about shape, size, and visual balance that scholars use when classifying and naming symbols in typography and mathematics, independent of any single language. The term DIAMOND marks the basic geometric figure, while CONCAVE-SIDED adds a surface detail that affects outline and weight in typographic design. These tokens help readers compare symbols, assess balance in a type specimen, and locate related figures in grammars or dictionaries that group signs by form. Practical usage contexts rest on a few core roles: in scholarly editions, the symbol appears as a geometric marker within mathematical notations and as a reference in typographic specimens; in educational primers, it helps illustrate discrete shapes and spaced alignment alongside other geometric icons; and in archival transcription, it serves as a consistent symbol in annotated texts for visual tagging of sections. Cross-platform appearance remains consistent with accessibility considerations for screen readers and high-contrast displays.
