Shell sits within the organic gem classification alongside pearl, coral, amber, and jet, materials defined by biological rather than mineral origin, and carries its own grading considerations in fine jewelry contexts.
Origin Story
Torre del Greco's position at the base of Vesuvius, on the Bay of Naples, put it in proximity to the Mediterranean coral trade and, eventually, at its center. For over three centuries, the town's carvers have worked coral and shell into relief portraits, mythological scenes, and botanical carvings, a geographic specialization that made Torre del Greco synonymous with the cameo craft worldwide.
A Storied Heritage
Wartime restrictions on platinum pushed Retro designers toward gold, and material scarcity shaped the design response. Bold, sculptural forms maximized visual impact with less stone material, producing an aesthetic of confident scale from constrained means.
