Thanks, nice to know that. I could guess that all the stones came from Mexico. Maybe

Another name for it is Cantera Opal. Often formed in small bubbles, or voids in the host stone it is usually cut leaving some of the matrix around the opal. Some of it is nothing short of spectacular!

Thank you, everyone
So, what is the best way to deal with the rocks. Just a specimen or try tumbling. It might undercut, maybe.

Google "Cantera opal" choose "images" and look at all the different ways they have been cut . I doubt they would very well

Good Snag Dale I probably would either keep them as they are or would sell or trade them. Looks to be too valuable for amateurs like us to do the job and set them right. Think tumbling would be sacrilege. What do you think after studying them more? Neat stuff and congrats on your good fortune.
