:help:
I am new to this fun hobby and have found a lot of info on the internet. I have found out there's quite a variety of polishes to choose from and was wondering what advice some of you more experienced folks may have for a beginner. On this site I have seen Titanium Oxide mentioned a few times. Plus what's the difference in Silicone Carb, Alum Oxide, Cerium Oxide, Tin Oxide, Chrome Oxide, Fused Alum Oxide, Calcined Alum Oxide & Sapphire power? I see there is a big price range so are the higher prices worth it?

If you are new to the hobby ... simplify.
Use silicon carbide (SC) for your grit (60/90, 120/220, 500). It is affordable and continues to grind even as it breaks down.
Use aluminum oxide (AO) for your pre-polish and polish (1000F, polish). It is affordable and will polish well for most starter material.
Once you have conquered the starter material (agate, jasper, quartz, petrified wood), experiment with more challenging material (obsidian, tigereye, sodalite) and try other poishes then.
