Agate Polishing Stone, Gold, silver, foil polisher and shaper (Polishing, Seal)

This natural agate polishing stone brings a jeweler's tool into the hands of metalworkers and decorative artists. Measuring 16–18 cm and shaped for an ergonomic grip, it's hard enough to smooth and seal gold and silver finishes without scratching delicate stones or metal work. Handcrafted from semi-precious agate, each stone is unique in color and ideal for bezel setting, PMC work, gilding, and polishing metallic surfaces to a luminous shine.
