Scorpio!

[Garabaldi]

There is a scorpion on this piece, which my be the symbol for Scorpio. From the two weld marks on the back, you think it was a cuff link? How old do you think this is?

Two "weld marks" make me think this cufflink is mid-20th century. Older ones would have a single "weld mark" in the center.

This link doesn't say anything about the jewelry other than 'vintage'

Not the same piece, but same maker/design.
