The color of the opalized wood does not alter how you cut it but the attributes of each source of wood you cut can alter treatment. The huge petrified logs in the pacific northwest are common opal also and typically very easy to cut and polish but I would not go out of my way to get it too hot. Crazing and brittleness can be  a problem with opalized wood as of course can be it's risk of being overheated and cracking or crazing.

Hi dede

I would take the slabbing a little more careful. Depending on the saw blade being used and feed pressure being used can cause bigger problems with fractures.

Love the pics and wish I had some of that material to play with.

Common as well as precious opal can be unstable. It may cut & polish beautifully, but after a year or so may start cracking for no apparent reason. Hopefully the material you have is stable & won't do this. I have a few chunks of Pacific NW opalized wood that I've left outside through several winters of freeze/thaw cycles. So far no cracking, so this spring I may slab it up.
