Agate Burnisher
What it is An agate burnisher is a handheld tool with a polished, rounded agate stone set into a wooden, metal, or plastic handle. Jewelers and metalsmiths use it to smooth, brighten, and compress metal surfaces—especially for finishing fine detail, burnishing edges, or polishing small areas where a rotary tool or cloth can’t reach.
Why use one
Produces a high-gloss, mirror-like finish on metals such as silver, gold, and copper without removing significant material.
Compresses metal, closing tiny scratches and tool marks for a cleaner, harder surface.
Ideal for finishing small details, undercut areas, and bezel seats around cabochons.
Safer on soft stones and delicate surfaces than metal tools: the hard, smooth agate won’t scratch most gemstones or soft metal work.
How to use an agate burnisher
Clean the metal surface of major burrs and solder residue first.
Hold the burnisher like a pencil and apply firm, even pressure.
Move the agate across the metal in smooth, overlapping strokes. For edges, follow the contour to keep the profile crisp.
For bezels, press and roll
