Vintage Women's 18K yellow gold with Amethyst stone earrings. 2.6 Grams.
Excellent condition. Could use a cleaning on underside of stone due to age. 
I attempted to clean with a regular tissue but did not work too well. A professional
jeweler would be better. Marked 18K Italy on the earrings. Listed as hoop earrings.
Not sure what style these are. Has a post and clamps down in back. See photos. 
Thanks for looking.
