What is rouge in jewellery making?

Definition
Rouge, in the context of jewellery making, is a fine polishing compound used in the final stage of bringing precious metal to a high shine. It is a soft abrasive, traditionally made from iron oxide which gives it its characteristic red colour, and it is applied to a soft polishing mop or buff mounted on a motor. After the rougher cutting and polishing steps are done, rouge removes the last fine scratches and brings out the full mirror finish on gold, silver and platinum. It is effective because the particles are so fine they polish without cutting.
Frequently asked questions
- What is rouge made from?
- Traditional jeweller's rouge is made from iron oxide, the same compound that gives rust its red colour. In its polishing form it is milled to an extremely fine powder and pressed into a block or mixed into a paste. There are also other coloured compounds for different metals and stages of polishing.
- How do you use rouge for polishing metal?
- You apply it to a soft cotton mop or buff attached to a polishing motor, then hold the piece against the spinning mop. The friction and the fine abrasive particles bring the metal up to a mirror finish. It is the last step in polishing, used after coarser compounds have already removed heavier scratches.
- Is rouge only used on precious metals?
- Rouge is most commonly associated with gold, silver and platinum polishing in jewellery making, but fine polishing compounds based on similar chemistry are used on optics, gemstones and automotive paintwork. In jewellery, the red compound is specifically associated with that final high-shine step on precious metal.
