Vintage Faux Turquoise Southwestern Style Clip Earrings

A pair of vintage Faux Turquoise Southwestern Style Clip Earrings from the 1970s. The mount is a metal alloy that closely resembles silver (but it isn’t). The faux turquoise looks amazingly authentic too (but isn’t either). The main stone has a nice matrix in it.  They have a nice polished surface.
