Vintage Sterling Silver Loran Sim Signed Screw On Earrings w Pale Blue Stones

Gorgeous pair of earrings that are fully marked, Loran Sim Sterling Silver. Sadly, I am not sure about the stone in them. To me it looks like aquamarine or topaz but it could be a colored rhinestone. My mom was the original owner of them. The earrings have a screw back to get them on or off. Great for adjusting how tight you want them as well. The stone in the center has a prong setting and the stone is an oval shape pale blue. The rest of the earrings are silver. The earrings measure about 3/4" wide by about 1" high. The actual stone measures about 1/4" wide by about 3/8" high. They are in nice shape as well. Pretty vintage set that will go with anything. Also, makes a lovely gift to someone special. Shipping in a gift box.
