Cab128 - 18x13mm Multicoloured sew on cabochon (1950-60s)

This is a multicoloured glass cabochon and is approximately 18mm by 13mm. The front of the cab is faceted- but the back is flat and there are two holes in the cab so it can be sewn onto material. The cabochon was made in 1950-1960 in a factory in Germany which recently closed.
