I have never see any earrings like these before.
They look like a type of hematite with many colors which seem to change with the light and as they are moved about.
They are signed Japan.
they are buttons and clips measuring 3/4 inch in diameter.
The are crafted in brass and are signed Japan We have purchased a huge estate, and we are pricing the items to move them out quickly because we find ourselves gravely overstocked....with so much more to list. You will find our prices extremely low. Be watching daily because the sale will continue until we have listed many more of these jewelry items.
