U+29EB "⧫" Black Lozenge Unicode Character

U+29EB "⧫" Black Lozenge is a geometric symbol that represents a solid, bold diamond shape, distinct from the standard white or open lozenges (such as U+25C6 or U+25C7) due to its filled appearance, making it useful for emphasis in diagrams, mathematical set notation, or typographic decoration. It belongs to the Miscellaneous Mathematical Symbols-B block, where it can serve as a marker for logical or spatial relations, and its opaque form provides strong visual contrast against light backgrounds, similar to a solid bullet but in a diamond outline.
