Pair of MCM? Pierced-Earrings, Unmarked, Odd Wire Latches

Transparent red, about 1 7/8" diameter, with a 7/8" center hole; they're each about 0.135" thick, an' as pic 3 shows, they're molded, so not Catalin/Bakelite.
Perhaps the hardware is an indicator of where/when made...I can only hope. They were in a free tub at a church rummage sale some years ago. Something about them said European...but I cannot now say what, exactly; probably wishful thinking. Thanks for lookin'!

 

Lucite/perspex?

 

Those wire latches are common, I'm wearing a pair of gold hoops right now that work the same way

 

Quite probably, AJ.

 

Can you say when, roughly, they were first used?

 

No, I have no idea, sorry.

 

I tried to pin down a date when the latch backs were first used but didn't have any luck. I know they were popular when I was teen in the '60's if that helps.

 

@Any Jewelry ??

 

They're still in use now.

 

I have several pair with that kind of wire.

 

Those wires were already seen in Antiquity, and are still used today.

 

Me, too!

 

Who knew? I don't wear the durn things...an' am usually unobservant of adornment detail while gazing fondly into my ladies' ears. I won't nibble on an earlobe burdened with such glitter, which they all know, an' most are accommodating of my peculiarities.
