The listing, Vintage Earrings WWII, Japanese, Pre 40's? has ended.
Sorry for the terrible picture!
These are some beautiful screw back earrings. I think they might be Japanese.
The white "stones" may be enamel or porcelain.
From top to bottom, they are about 1 inch. The top white "stone' is round and the bigger one is tear drop.
They have the vintage screw backings.
Beautiful piece of history!
