so I'm still experimenting/learning
I have a nice piece of stone that I decided to do a free from cab from. I have some buffing wheels and buffing compounds but it won't shine up the stone as much as I want, I used jewelers rouge and trilopi and gives them a dull shine but not the high gloss I'm after. any suggestions? thanks.

If you mean bars of tripoli and rouge on soft flannel buffs you are using metal finishing stuff. A leather or felt buff with aluminum oxide, cerium oxide, or tin oxide would work better. Or diamond compound which polishes most stones. Powdered tripoli (mixed in a paste and used on a buff) works for some stones. The sunstone guy at Quartzsite used it exclusively. I sold out of powdered tripoli because of him.

I see there are several different oxides etc for polishing, is there a tutorial as to what to use for different stones? it all gets rather confusing. Different substances and different grits.

Covington Engineering website has a polish/buff chart that shows many rocks with best choices of buff and polish to use. Keather works well on most rocks and .3 micron aluminum oxide will polish both hard and soft rocks. The Linde A listed by Covington is also a .3 micron aluminum. Diamond compound also polishes just about anything.
