The listing, Vintage Pierced Threaded Post Earrings has ended.
These are vintage late 19th century or early 20th century threaded post (circa 1895 I believe.) These were my Grandmothers and given to her by her Brother. All original even with the keepers.
Pink stones with beautiful sparkle. The earring posts are threaded along with the keepers. They act similiar to threading a bolt. The earring back twists onto the threaded post to hold the earrings securely in place. This type of earring is rarely found today.
To remove your earrings hold the backing of your antique threaded back and rotate it to the left to move it towards the end of the post and into your hand..
I've tried to show the threading of the posts and the orginal keepers. Size is shown by the photos with the ruler.
I know the photos aren't great but at least hopefully you see through to the beauty and age of these.
No markings that I could find on these.
