✅ SOLVED Button Mystery - Omega?

[ANTIQUARIAN]

I found this button on a long gone homestead site east of Toronto.
This button is definitely a mystery to me... it's made of black glass, it had a metal loop in the back and I have no idea what the symbol means?

Any thoughts as to whether it has religious significance or possibly a school fraternity or it's age?

Thanks very much,
Dave

Thank you very much for the information Bramblefind, I had no idea this could've been a mourning button!

Thanks again for your help,
