Are these beads a mixture of selenium and cadmium? They seem to be possibly Czech glass beads.
Normal light, 365nm, 395nm (the two last photos taken through my glasses with blue light filter.
(The other pink beads are an early plastic)
Hello,
I got these buttons for around 1 dollar/euro in a thrift store. I think they are moss agate, but then someone suggested that they could be jade.
I have tried to compare these buttons with pictures online of jadeite and moss agate, but I am still not sure what mineral they are. I have not tested the metal, but I think it could be gold and silver.
I would be very thankful for any thoughts on the mineral.
Add: they are not UV-reactive (365nm, 395nm)
