Linn is right in that they could be either German or Czech (I saw Czech also) since there is so much overlap, especially during that time, when Bohemian factories manufactured glass stones for the 'world' (with the exception of Italy and Japan, which lampworked their own).
So when you list the German pair, you may want to include in your description that they are Czech glass (cabs), so that you get these collectors, especially when they keyword search.
The cameo style beads (the green ones) are same (Czech) as mentioned earlier. The molded glass is often made to look like carved Fiance, along with a paint 'residue' added for an antiquities look.
I've had many of these in different motifs, usually Egyptian and/or in the classical style such as your pair -- however, I don't have any examples in my collection to show you right now, and the last listings that I sold on ebay, are long expired.
I strongly advise however, that you mention that they are either crafted, upcycled or a marriage (which they are) -- since those chains and clipbacks are *not* original to those beads. Those beads are late 20's/30's, the chains are contemporary (within the last 20 years or so) and the clipbacks are likely to be 50's or so.
Lots of folks buy upcycled and 'vintage style', so they should do well.
