Vintage Native American feather pink feldspar? Crystal earrings sterling silver

Vintage Native American feather pink feldspar? Crystal earrings sterling silver.

These are definitely vintage and have a bit of tarnish on them I can polish them if desired. I believe the gemstone/crystal is pink feldspar one of the stones sparkles more than the other and has tons of rainbow color and it almost like an opal. The earrings dangle nicely.
