Writers have long employed the color sapphire to evoke feelings of depth, brilliance, and otherworldly majesty. For example, sapphire is used to capture the luminous quality of eyes, as in descriptions where a character’s gaze is compared to the clear, sparkling essence of sapphire ([1], [2]). The color also paints vast, celestial scenes—the “sapphire vault” of the sky ([3]) and expansive bodies of water that shimmer with an intense blue glow, as when the sun sails through a “sapphire sea” ([4], [5]). At times, sapphire becomes a metaphor for the grandeur of nature itself, with landscapes such as the Mediterranean recast as an immense, gleaming sapphire ([6]) or the fading light of day evoking a “sapphire dusk” ([7]). Even the heavens are not spared, being rendered in tones of “clear sapphire” that imbue the narrative with ethereal beauty ([8]). In these ways, sapphire serves as a powerful and evocative symbol throughout literature.
