The mark is oval shaped, and looks like the Batman icon, or perhaps some sort of axe or flower.
Can anyone help identify this mark? Is it a country mark? Maker's mark?
The photos of the mark are below, along with the picture of the earrings (15mm diameter).
(Sorry for the picture quality, the mark is very tiny; less than .5 mm and on the earring pin. These were taken with a 20x loupe)
Any help would be greatly appreciated.
