American made a walnut plaque with a caduceus antique bronze casting and black brass engraving plate that engraves gold. Please disregard the engraving in the photo - it is not ours! We rotary engrave these using a diamond cutter and complex fill patterns to cut into the metal. This makes for logos that pop and text with depth that sparkles and catches the light. We do not laser engrave metal as it makes a flat, lifeless award.
