Ronan was spotted wearing her new ring for the first time since she and Lowden tied the knot last month, as she walked out to the premiere of her new film The Outrun in Edinburgh on Thursday.
While her gold ring wowed on the red carpet, the actress' chic sequin dress also sparkled on the night, which also saw her wearing a necklace and pair of earrings.
Lowden and Ronan married at a low key ceremony at Lowden's native Scotland at the Edinburgh Central Registrar's Office, attended by a small number of guests who were also sworn to secrecy to avoid attention from the paparazzi.
The couple began dating six years ago, having met on the set of Mary Queen of Scots in 2018.
Jack Lowden also co-produced The Outrun alongside Saoirse Ronan, which arrives on September 27.
