This is a Vintage pair of Karl Jorgen Otteren clip on earrings. They are made of sterling silver and shades of blue enameling. They measure approximately 3/4" long and approximately 1/2" at their widest point. They are hallmarked on the inside back of each earring.
The hallmarks are a little hard to make out. The clip backs work properly. If you have any questions please feel free to ask.I do not clean or polish my items. I sell them as I receive them.
