Vintage Stamped Made in West Germany Clear Glass Intaglio Cameo Brooch Pin

Vintage (my research places this Mid Century), Beautiful Condition, stamped “Made in West Germany”, feels like glass (not confirmed by a professional), cameo is cut or carved into the back side. 25-Clear rhinestones around gold tone metal frame. Cameo and rhinestones are all held in with many prongs (not glued), 4-prongs around each rhinestone, and 35-prongs around the glass oval which also has cuts around the edges throwing off light so beautifully! Cameo and rhinestones all feel secure at this time. Some photos taken with overhead light on, some taken in natural lighting. No filters used. Callout: bottom edge of pin along filigree is slightly bent or turned up (pic #6), not noticeable when wearing, only when looking at it from the bottom of the pin as shown in picture. Will ship in the vintage hard case jewelry box shown in last picture. This is not the original box, so please ignore any & all information printed on the box interior; it has nothing to do with this item. This just happens to be the box the pin has been stored in for decades and will serve well for protection during shipping. Gorgeous details on this gold tone brooch and really nice piece of stamped history!
