The Production Process

Balancing innovative technology with traditional techniques of ancient metal casting, Buy A Stone rings require the latest technologies of modern 3D printing to capture the complexity of the lattice designs. The intersecting lines form enclosures, making the rings impossible to manufacture using common methods of molding. Instead, each metal ring begins as a wax ring that is printed using a high precision 3D printer. Taking hours to print, this unique 3D printer creates layers of two different materials, one material is support, and the other comprises the castable wax ring. After heating, the support material melts away to reveal the delicate wax ring. The wax ring is then cast using an ancient "lost-wax" casting technique, in which the wax ring is placed in an investment plaster to create a single-use mold. Using a centrifuge, the molten metal is forced into the mold to fill every intricate intersection. Each ring is then finished by hand.
