Vintage lot of screw back earrings. The flowers are stamped Mexico but are covered a little bit with solder. They are MOP and onyx.

The turquoise stars are stamped sterling on the top of the screw back.

The oval turquoise earrings were made in Mammoth Arizona by a local artist in the 1970s, but I do not have the name.

The round green turquoise earrings  appear to be costume.

The hoop Kachina is not stamped.
