KATE Johnson had resigned herself to the fact she had lost the first ring her late husband Kevin ever gave her.
But the power of social media, and her four tech-savvy daughters, has reunited the Toowoomba woman with the inscribed gold ring.
"About two years ago, after my husband passed, I went looking for it, turned the house upside down, but couldn't find it," Mrs Johnson said.
Where the ring has been for the past two years remains a mystery and the exact date it was lost is unknown.
It was found in the bottom of a charity bin in Kearneys Spring with other stolen jewellery and a worker handed it in to police late last year.
Mrs Johnson and her daughter Melita Ewing are adamant it was not stolen from the family home.
It was only after Kevin died suddenly from a brain bleed in March, 2013, that Mrs Johnson stepped up the search for the sentimental keepsake and realised it was lost.
Kevin gave Mrs Johnson the ring inscribed with the simple message "Kate love Kevin" and the date 10.7.75, for her 19th birthday 40 years ago.
It was a friendship ring, and the same engraving is on Mrs Johnson's wedding band marking the date they married later that year.
"It was the first ring Kevin ever gave me so I was a bit upset when I couldn't find it, even though I hadn't worn it for years," she said.
"I can't see that it would have been stolen, and the only thing I could think of was it got thrown out when I threw out some clothes."
Mrs Johnson's daughters including Mrs Ewing saw the ring mere minutes after it was posted on Facebook Monday morning and immediately called each other, asking if they thought it was their mum's ring.
Toowoomba police held back part of the engraving, but there was enough published for Mrs Ewing to know it was from her dad.
"My sister had texted me and called me and said, 'get on Facebook and have a look at this ring'," Mrs Ewing said.
"I had a look and said, 'oh my god! Its mum's ring', because I remember the engraving.
"I popped down to the police station and they were just dumbfounded that this ring had just turned up."
The family took the ring's discovery as a sign Kevin was watching over the family; given it was one of Kevin's granddaughter's second birthday on Monday.
"We were a bit giggly because it was my sister's little girl's second birthday (on Monday) and she didn't get to meet dad, so we think it was dad looking down on us," Mrs Ewing said.
She said it was lucky it had been handed in to police and eventually reunited with her mother.
"We'd love to know whoever it was that handed it in," she said.
"They could have just ignored it and it never would have been handed in."
