Faux green opal earring drop

I love these gem look-alikes. This glass piece was made in Germany immediately after WWII. The box I found it in was marked "Germany-U.S. Zone" so we know it is vintage for sure! The glass has a lovely luminescence about it and is shot through with black highlights. The centerpieces are set in sterling silver. The centerpiece is 10 mm by 12 mm. The drop is 17 mm long including the loop. Price is for a pair.
