Antique pendant discount around 1900 Silver ball chain pendant

Antique pendant made of silver.
It is held in the form of a ball.
The ball is not quite round - rather oval worked on one side.
The length is about 2.5 cm and the width about 1.9 cm
It is an old piece with age-related traces.
Partly tarnished, dents available etc.
The condition is as seen in the pictures.
The pendant is stamped, only with a master punch. Unfortunately, I can't quite assign them. Tested for silver and discount confirmed.
A beautiful old piece of jewelry
