trending ! RARE Vintage Antique German indent Glass reflector christmas ornament

a vintage German Christmas ornament, specifically a "reflector" or "indent" ornament, likely dating back to the early 20th century. This ornament is characterized by a concave indentation on one side, with a mirrored interior that reflects light and enhances the ornament's visual appeal. The exterior of the ornament is silvered glass, with a frosted or "snowy" texture around the edge. Inside the indentation, a smaller, multicolored glass ball is visible, adding another layer of reflection and visual interest. These types of ornaments were popular in Germany and later exported to other countries, including the United States, from the late 1800s through the early 1900s.
