14K White Gold Hollow Knot Earrings Made in Italy Omega Back Estate Statement Earrings

A simple but striking form in 14k white gold from my Mom's estate. These statement earrings were likely purchased in the early aughts. I have seen exact matches for sale online, but I wasn't able to identify the designer.

Made with polished 14K white gold, they seem to be fully hollow and feel incredibly light.
