Super Cerium Oxide Polishing Powder (<2um) 100g

A premium grade cerium oxide for a price closer to a standard optical grade cerium oxide.
Usually $22.5 per 100g.
 
For polishing stones a minium of optical grade cerium oxide (typically between 3-3.5 micron) is a must.
However, a higher quality option (commonly refered to as super cerium oxide) is far better in terms of final result and efficiency, speeding up the process with a less than 2 micron particle size.

The softness of cerium oxide makes it the number one choice for polishing Australian opal and many other sillica based stones due to the perfect balance between the chemical and mechanical polishing effects.

This is my #1 recommended polishing powder for Australian Opal from Lightning Ridge, Coober Pedy, White Cliffs and Andamooka.
