Item: Vintage Art Deco Sterling Silver Marcasite Red Stone Leaf Earrings. These are stamped Sterling. The red stones are small and I can't get an accurate test on them. I'm going to say glass just to be safe. The display box is not included in the sale of the earrings.
 
Measurements: 1 & 1/8th inches long.
 
Condition: Vintage, previously owned. One of the red stones is damaged (it's pretty small, so it's hard to notice). There are other minor signs of age/patina/wear.
