Ambar Lapidra has been prized in the Iberian Peninsula since Roman times. Romans called it lapis specularis in some contexts, though that term was broader. They used it for intaglios (engraved gems) and small decorative objects, valuing its warm glow and ease of carving. In medieval Catalonia, it was known as pedra d'ambre or ambre de pedra and was often set in religious artifacts and rosaries, as its golden hue symbolized divine light.
