Help ..... is one kind of cerium oxide better than others for polishing agate cabs? I have looked and see so many brands. I just get baffled. I baffle easily but this is ridiculous.
My frustration is with not knowing if I am getting the BEST shine on agate (and jasper). It may be that I am and that will be ok. Also I have a piece of Noreena Jasper that I am sure will take a better shine than I have now. It's pretty but should be better. Thanks again, Don

I use the generic cerium oxide with perfect results. Noreena never gets a glassy polish to my knowledge. Bob

Cerium oxide does come in different grades, the lighter the color the finer the grade and the higher the price. I really like Tin Oxide on a felt buff myself, its not always successful so I have all sorts of polishes (Al Oxide, Chrome Oxide and Diamond) and buffs (felt, leather, wood ) and just try them all until I get something that works.
For the jaspers that undercut and are difficult to polish I find Chrome oxide sometimes works. I have seen it mentioned on here people using a rag buff and Zam with success (Zam is Chrome Oxide.

Can't help with the abrasive, but I can tell you that some noreena will polish better than others, but none will be glossy.

When I was polishing on a 12 inch leather wheel, I always added a bit of Linde A to the the cerium oxide for most agates and jaspers.. As mentioned above, not everything will take a mirror polish
