Never heard of it. Facetors use a variety of oxides: chrome, aluminum, cerium, zirconium; but iron must not be much use.

I may be mistaken, but I believe iron oxide is what gives red jewelers rouge it's color.

Yes, it's jeweler's rouge used for polishing gold and silver. I know of no specific lapidary use.

At mohs 5 and below it might do some good, but since it's also basically red pigment, clean up might be a chore.

We Use it as a pigment for soils. As careful as you are you are red at the end of the day. I believe about. One 364th will color a bright red. I wouldn't use it,the rivers would run red. You could never wash it out. Three showers and the towels are still pink.

Isn’t that basically what gives red dirt shirts their color?
