These are fairly old/ The first picture has it sitting in it's aged wrapper. Light blue glass crystal cabochon the edges of this are faceted and beveled to the front and the back. Quite thick measuring about 13mm tall. Not going to work in all settings. Prong settings, open back settings and wire wrapping are a good choice. I had an open back setting I used to show example. A vintage piece no longer being produced. Made in Germany,
