Thanks for the warm welcome everyone!
That's good to know that petoskey stones can still be collected. I haven't been to that area of Michigan in years, but it might be worth a side trip when next I visit Wisconsin. :)
I was just in Arizona a couple weeks ago, though I was in Scottsdale, rather than the north. Arizona is one of my all-time favorite states, and when I spent several years full time RVing, Arizona was my winter home. Someday, I might move back there. Some of my favorite people are there, including a whole bunch of folks with greyhounds, whippets, and Italian greyhounds.
I'm thinking of buying a petoskey cabochon to use in a ring. I've got my eye on a particular one that I think would be gorgeous, and quite nostalgic. I'm just doing some more research on what I want before actually buying anything. I can't afford to buy everything I like. I'd be broke inside of an hour (or less!!!).
