For Anne Hathaway
, there's no better place to show off a new diamond than on a walk through the park.
The actress, who recently got engaged to Adam Shulman
, was wearing her engagement ring when she stepped out Sunday in Brooklyn's Fort Greene Park with her new fiancé and her dog, a chocolate Lab named Esmeralda.
Shulman designed the ring in collaboration with Kwiat, whose diamonds are certified conflict-free. "Adam did work with us to design a ring that he knew Anne would love," owner Greg Kwiat tells PEOPLE. "He had a very strong vision for what he knew Anne would love."
The trio enjoyed a gorgeous fall day in a Brooklyn park, where they played fetch and sat together in the autumn leaves.
Hathaway and Shulman even indulged in some PDA, sharing kisses while Shulman kept a hand on Esmeralda's leash.
The dog has been through thick and thin with the actress; Hathaway once shared Esmeralda with onetime boyfriend Raffaello Follieri, and the dog was staying at Follieri's apartment
when FBI agents arrived to arrest him.
