In literature, "agate" wears many faces—sometimes a literal gemstone and at other times a rich metaphor. It appears as an object of ancient wonder and a marker of refined beauty, as when fantastical tales imbue it with almost mystical qualities [1] and list it among other precious materials to emphasize exotic and grand settings [2, 3]. In some texts, agate is not merely decorative but functional, serving as a tool or material in art, craftsmanship, or even culinary processes [4, 5, 6]. Moreover, its description often lends a subtle insight into character or atmosphere, from sparkling eyes that betray a hidden nature to lavish architectural embellishments that capture an era’s opulence [7, 8, 9].
