can you help me please?

i have seen buttons like this in a "marcasite" colourway
but not in a goldtone before, they are glass
and they have a 4-way brass shank

***

these are unusual too
they are glass with a faux printed silk effect to the centres,
the rim and colour remind me of victorian jet mourning buttons
but the floral pattern makes me think 1950's

these also have the 4-way brass shanks

Please can you help identifying the age of these buttons?
Any help greatly appreciated :0)
