A brass balance with two shallow pans mounted on a fulcrum, calibrated to weigh precious metal and gems in carats and ounces. Goldsmiths and gem-merchants depend on such scales to price their work and confirm the weight of bullion or cut stones. A well-made jeweler’s scale is sensitive to a single grain; fraud is possible but costly—a crooked scale ruins a master’s reputation and may draw the lord’s justice.
