Permabrass vs gold hardware
A thinner gold plating that shows the brass.
Christie's says permabrass hardware has gold plating no thicker than 1µm, so the natural light gold colour of the brass shows, and lists it among options for custom or limited horseshoe-stamp bags. Standard gold hardware is brass plated with fine gold, according to Hermès.
