A nanny who lost her diamond ring in a Tribeca playground has been reunited with the bling two days later thanks to a family of quick-thinking good Samaritans.

Joyce Bermuda, 52, told The Post she was devastated when she realized three pricey bands — birthday gifts from her husband — had slipped off her finger while watching her employer’s tot at the Pier 25 playground on Monday morning.

“After lunch, I realized I didn’t have my ring. I was very upset,” Bermuda said. “I was really sad.”

She went back at 6 p.m. after finishing work but couldn’t find them and thought they were lost forever.

Unbeknownst to her, a family visiting from out of town stumbled on the rings and scooped them up — waiting at the park for several hours for the nanny to come back before leaving a note.

Boston-born Kristen Woodiwiss, who lives in South Korea and was vacationing in New York, found the rings while playing with her two young daughters.

“My daughter asked, ‘Shouldn’t we just leave them?’ and I said, ‘No, we’re going to try to help,'” Woodiwiss told The Post. “So we stayed for a few hours and decided to leave a note.”

The note had their contact number and said they were dropping the bling off at the 1st Precinct — but unfortunately it got drenched in Monday’s deluge and ended up beneath a bush where Bermuda couldn’t see it.

It was Woodiwiss’s mother, Terry Prescott Marshall, who thought to also announce their find on community website Tribeca Citizen — which was eventually spotted by Bermuda’s employer.

Officer Daniel Donadio from the 1st Precinct delivered the happy news that they had her bounty and Bermuda reunited with her bling on Wednesday morning.

“I texted Kristen and said thank you and I’d like to meet you personally and thank you personally,” Bermuda said. “I want to give credit to them, my boss and the police officer.”

“If they’re ever back in town, I hope they hold onto my phone number and reach out to me to meet.”

“I’m just so thankful that we found her rings,” Woodiwiss said. “Obviously they’re very special to her so we’re glad she was reunited with them.”

“It’s a really happy story,” she said.

Bermuda said she was overjoyed to have the rings back — but after this close call, won’t be wearing them any time soon.

“I’m going to keep it in a safe place at home so I don’t lose it,” she said.
