I agree with Mohs, start with some onyx or serpentine. It will take a third of the amount of time as a BC agate will.

I made a jig to hold the block that I clamped in my saw vise. All the angles and cuts were exactly the same.

This might be of some help. As far as material the biggest thing is fracture free. It is very frustrating when you get part way through a piece and you have a blow out.

It just confirms what I decided a few years back, making spheres is not for me. All the work with the saw seals the deal. |

There is always the option of a core drill. That saves tons of time on your preform.
