This green powder is helpful in polishing green rocks. It is messy to use, and leaves a green tint to everything it touches. A great polish for jade, garnets, rhodonite and lapis because it tends to minimize undercutting. This product is dark green and has a particle size of 3-5 microns. Shipped in a 1-pint plastic container with a snap-on lid. This is 0.8 pounds of Chrome Oxide powder, at $15.56 per pound.
