It's one of the most special parts of a wedding ceremony - the exchanging of the rings.
But, for one couple who married on Saturday it brought a shocking realisation.
Jessica and Jarrad Eynstone's wedding ceremony at Kiama on the NSW South Coast came to a crashing halt when the celebrant realised the bride's wedding ring had vanished.
"When we got there the rings were on a pillow and when the celebrant asked for the rings, my wife's wasn't there," Jarrad said.
"My heart just sank."
Wedding guests quickly started searching for the missing ring, to no avail.
In an unexplainable turn of events, Jarrad's mother Gaylene Eynstone said a local man well-known for his metal detecting skills appeared at the ceremony.
"Someone said 'we need a metal detector' and all of a sudden this man was there, we don't even know how it happened," she said.
"He had a look but too many people had trampled the ground looking for it so he gave me his phone number and said he would search later."

While Jarrad said the couple was both devastated, the ceremony went on and Jessica used her engagement ring as a stand-in wedding ring.
Not wanting to give up, Gaylene joined a Kiama Facebook page to spread the word of the missing ring.
On Sunday the family received some happy news. The ring had been found.
While she didn't get his name, Gaylene thanked the "man with the metal detector" who later found the ring trampled into the ground.
"We just couldn't believe he found it, he's a beautiful soul and we can't thank him enough," Gaylene said.
"We offered him a reward but he wouldn't take it, he said he was just happy to see it returned."
The ring, which is engraved with the words 'Forever and always J&J 6/4/2019', has now been returned to a thrilled Jessica.
