The middle picture looks like Tiffany Stone, which is an opalized berryllium fluorite from Utah. I know it has a variety of appearances so all threee might be the same material. It is fairly soft, but it does take a good polish. Do use a light hand, it will undercut in spots.

Tiffany stone for sure. I have some with oranges and browns and a piece that looks exactly like the first one. You have some really nice material there.

Yup, Tiffany, also known as Bertrandite and I agree, it can be a bit problematic to work....Mel
