In literary descriptions, "obsidian" often serves as a vivid metaphor for a deep, reflective black that carries both beauty and mystery. Authors describe landscapes and objects using obsidian to evoke a sense of inky darkness and sleek, glass-like texture—for example, vast masses “composed of obsidian, pure, and black as jet” create an atmosphere of impenetrable night [1]. Similarly, natural formations are rendered with a dramatic flourish, as cliffs are imagined “as though they had been carved from obsidian,” emphasizing their smooth, enigmatic surfaces [2]. Occasionally, writers even hint at subtle variations in this tone, as in depictions of “dark green obsidian” that add an unexpected layer of richness to the color [3]. Through such images, obsidian becomes more than a mere stone—it transforms into a powerful literary symbol of dark, captivating allure.
