Jacques Marie Mage Fellini - Jonathan Majors - Creed III
Jacques Marie Mage is a relatively new eyewear brand, founded in 2014, but already showing up on some major actors in big Hollywood productions, like Jeff Goldblum's glasses in Jurassic World: Dominion and Brad Pitt's glasses in Babylon.
The glasses in the film seem to be the Fellini model, in black or tortoise shell, with a visible, gold wire core design and details.
Jacques Marie Mage usually makes each color variation of a model in a limited edition of 500 pieces, at a price of $750. This particular color seems to be sold out but you could contact Jacques Marie Mage via their website to see if they still have the model in stock.
In Creed III, actor and director Michael B. Jordan wears a pair of Coach sunglasses.
