Vintage 936 Turquoise And Coral Clip Earrings

Vintage 936 Turquoise And Coral Clip Earrings . These are beautiful vintage clip on earrings.  The only marking i see is a 936 on the back of each earring. The stones appear to be Turquoise and small ones that are Coral color so im assuming they are coral.  They have some weight to them,  like that were high quality in their day. The clamp part that goes on your ear has Pat. Pend on each one.  Please see pictures for more details and a measurement compared to a US coin. Coin not included.
