This allows for an exceptional polish on glass, stone and jewelry items. This is the preferred polishing material of choice for many lapidary and jewelry applications.

Use with flat lap polishing machines for a beautifully smooth surface. It is also useful for removing light scratches from glass surfaces and mirrors.

This cerium oxide is packaged in a convenient, ready-to-mix bottle. Just add water according to the directions on the bottle, tighten the cap, give it a shake and you’re all set. A foam sponge applicator brush is included with each bottle of polishing powder.

Roger King
Super Polish

I have tried many different types of polish and the Cerium Oxide Powder is the best for the type of rocks I polish.

Cerium Oxide

I use 3 different compounds. Cab king 14k & 50k, Zam, and Cerium Oxide. So far the Cerium is the only solution to a perfect scratch free shine on soft stones like Flourite and a few others.. like unstabilized turquois. It has its place in the polishing lineup and works great.


The polish helped also with the scratches on the stones. Very impressive.
