some tile saws, by chance, had a fairly good blade. The old HomeDepot WorkForce got famous because it happened to have a surprisingly good blade.
Husky and HotDog are good tile saw blade brands. Some no-name are good too, but it is hit and miss. Expect to pay $30 to $45 for a good blade. It might be best to get an OK blade rated for hard stone for about $18 and practice handling the rock and especially the rotating trick. Then get the better blade. you could also get something soft like a brick or piece of limestone and practice handling and rotating with the blade the comes with the saw.
if the geodes have agate or jasper in center, you might tumble if you cut to small enough pieces. You can put half of a 1.25" geode in most tumblers if smaller rocks are present. You can't put half of a 3" geode in a tumbler unless it is a larger model.
tumbling takes a long time to get marks out of an otherwise flat surface, because the whole surface must be worn down. it works better on raised bits.
you might consider polishing the faces using grit on a glass plate. you might also make an inexpensive flat-lap following designs in the homemade equipment section.
