K&L Germany pendant and earrings

I found these two sets (pendant + ”screw” earrings) from my grandmother’s archives. They are both marked ”AM BOUBLE” and ”K&L”, so obviously they are made by German Kordes & Lichtenfels and they are gold plated (amerikaner doublé). They have purple and orange colored glass stones (citrine?) and has no visible defects. They are most probably from the 60’s.

I would be grateful if someone had any additional information about these and if I end up selling them, what would be a convenient price for the sets?

Thanks a lot!

Kordes & Lichtenfels is a good costume jewellery brand. Their AD jewellery is likely to have glass stones, as you suspected.
We don't advise on values, but you can look on ebay and similar selling platforms what K&L jewellery sells for.
