This pin confuses me...

[lordirae]

Is it older or do I just get that vibe from it? I am absolutely horrible at dating pieces but can usually fake it enough to get through it...not so this time.

My gut reaction to this pin is that it's from the 1960's.

has a retro modern feel to me. Remiands me of a comet actually

How are the chains attached to the back of this brooch?

[lordirae]

Looks like a jump ring...please excuse my chubby fingers!!

[lordirae]

Thanks for that comet KW.  After looking around based on that, I think atomic would be a great KW for the title!

Is the stone Plastic (Acrylic)?

[lordirae]

Nope. Taps like glass.

If it were plastic could mean aa date of (late) 40s, early 50s.
