I made this pendant from an authentic 1930's brooch. It features hemetite colored rhinestones and Peking glass set in metal. I removed the hardware from the back and added a glue on bail. I use two part epoxy resin as glue and it has a hardness on the mosh scale of 7 which is about as hard as quartz. With care, this will last 100 years or more.
The last picture shows another example of Peking glass which is not included in this listing.
