Olah Gia, welcome.
If you are using a dremel type setup(hand held mutli drill tool). You will need to aqiure sanding bits in order to further work your piece/s.
Often we shape/carve with hard(metal) type bits. These often are around a 100grit, which is great for shaping. but you will need higher grit "soft" bits(200 and above) Ideally you should get rubberized bits, like these
"Lasco sells Diamond bits"notice they have them in 240, upto 1500 grit size. These, in secession, will sand your carvings. They will not polish them. In order to polish, using the same method, simply get
"felt bits" In which you also get
diamond polishing compound, load the compound to the felt bit, and use just like the others. Be warned you need each its own felt bits for each polishing stage you do. As with sanding, pre-polishing certain materials can benefit. For example, fire agates do well when pre-polished, i shape on 80grit, sand from 100,220,400,600 grit silicon carbide, pre-polish starting at 1200, then 14,000, and 50,000 diamond compound. And in some cases i do a final polish using Optical Cerium.
however, Turquoise you can sand up till 600 grit, than polish using ZAM compound and be done. So it all depends on the material your cutting, and in time, you develope your own method of process when sanding and polishing. No matter the form or method used. Hope this makes sence and is not too confusing.
