Gemology and beliefs: Opals come in various types, with noble opals being the kind that exhibits play-of-color. This captivating effect is caused by tiny, uniformly sized spheres of silica. When light hits these spheres and is refracted, it produces a dazzling display of colors on the opal’s surface. In contrast, common opals lack this play-of-color, as their spheres are disordered and of varying sizes, giving them a milky appearance. Opals have been associated with the power of invisibility in folklore, earning them the title “Patronus forum” (patron of thieves) during the late Middle Ages.
