Pink swirl rock ID help needed

[2Minnesota]

Can anyone help ID these stones? I believe they came from the USA. They are in a vintage Native American jewelry piece. Thanks for any help offered!

It's a variant of Ocean Jasper.

It's the mineral Rhodochrosite. The black areas are Manganese ore.

It's a pretty common semi precious stone used in silver jewelry.
