Couple of things: GM and the website say “carbon fiber style” or “look”. The website linked above says “The top cap of this shift knob has a smooth feel with a carbon fiber texture appearance which includes the Heritage Camaro Logo outline.”

And it is not $155 for just the cap. It includes the entire shifter. That said, yours shouldn’t fall off. I’d get it fixed under warranty if you bought it from GM that way.
