A friend of a friend is selling these:
BLACK HOLE SUN
Black vole skull earrings in decorative metal frames.
This is a unique pair of earrings. The vole skulls were found in barn owl pellets in South Ayrshire. I thought they would look good with the metal earring frames. I am please with how they look now.
