a few non-earring things from the costume jewelry lot

More from the 'bonanza', these items don't quite fit with all the rest...?

From top left, clockwise:

a) 3 pcs delicate rose shaped lapel pins, these might actually be porcelain, with a rhinestone inset in the center of each
b) pair of goldtone pierced earrings
c) silvertone lapel pin angel with tiny dangling star
d) butterfly pendant, goldtone filled in with ?? material (enamel? glazing of some sort??)
e) pair of lapel pins with 4 rhinestones each
f) actual pinback button with photograph (?) of an elegant lady's face

For the record, I'm not certain if "lapel pin" is the correct term for those labeled as such -- if there's a better word somebody please give me a hint! Otherwise I don't believe I've ever seen actual earrings with that type of fastener back, that and the fact that there's three of the rose ones suggests against 'earrings' to me...

ONCE MORE -- if anybody wants more info or closer pics of anything, just let me know and I'll see what I can do! :-) :-) :-)
