Go to harbor freight or one of those knock-off stores.
Don't know about diamond blades, but I've used many regular blades that seemed to work fine.
That is what is nice about the coral saw, the cut rest is plastic rather than stainless or other metals, so it doen't get all rusty.
Regular blades will work, but will dull much quicker than the diamond blades and begin to tear rather than cut coral tissue. Even the diamond ones dull, but they last a lot longer.
