Sunstone is easy to polish, but the problem I’ve had is finding rough that’s deep enough.
You may indeed use synthetic corundum. Unless you happen to have a chunk of ruby big enough 🙂
There are synthetic glasses with higher refractive indices. I’ve used Jewelite, laser gems and Nano-sital. TVite is pretty good, too.
