I have a story about a lost and found ring:
My dad was in the Air Force and we moved often. When I was about 10, we moved to a new assignment and settled into our house on base. In the bathroom, there was a super ugly mirror/vanity/cupboard that had been installed many years before and it stayed because it was a permanent fixture even though it wasn't "standard issue."
One afternoon, my friends and I were playing softball outside and someone hit the ball pretty hard -- and it went right through the open bathroom window and smashed into that ugly mirror, shattering it. We didn't know it had shattered the mirror until later when I went home and I found it.
I began picking up the pieces thinking I was going to be in such BIG trouble... and then on the floor, in the middle of the broken glass and mirror, there was a diamond and ruby ring!
My parents came home later that night and I told them what happened and showed them the ring. They looked very carefully at the remains of that ugly cabinet and could NOT figure out how the ring was in it. My dad thought that maybe it had been caught on an inside hinge and came loose when the whole thing broke.
They took it to a jeweler and found it it was a platinum antique "scrolled" setting with a diamond a little over 1k. On each side of the center diamond, there were 2 ruby baguettes. Very unique ring. I know they tried to contact previous occupants of the house to find the owner, but that was hard to do with so many families moving in and out. They never found the person who lost it and my mom stuck it in her jewelry box and held onto it.
Fast forward 8 years later: we are at another military base and my parents attend an engagement party for the son of one of their very good friends. Sometime during the party, the hostess mentioned that she had hoped to pass on her original wedding ring to her son for his wife one day but that she had lost it many years earlier. Then mentioned that it was originally HER MIL's ring and that her husband had added ruby baguettes to it (signifying something but I can't remember what). My mom about fell out of her chair when she heard this!
My parents stayed afterwards and asked more questions about the ring. They realized they had found the owner of the ring my mom had kept all this time. My parents were overjoyed to tell them they had found the ring 8 years earlier -- and the couple was overjoyed to have the ring returned to them! It was such a crazy coincidence!
The woman had removed the ring from her finger 20 years earlier when she was pregnant and the ring had become too tight. The ring disappeared after that and they never found it. They kind of thought one of their other sons (ages 2 and 3 at the time) might have picked it up, carried it around and dropped it outside. She was heartbroken at having lost a very sentimental ring...
They DID live in the same house we were in when we found the ring -- they had lived there 12 years earlier. They are the ones that installed the ugly mirror! They couldn't remember if the mirror was installed before or after the ring was lost... and we never knew for SURE that the ring was in the cabinet -- but breaking the cabinet made the ring re-appear.
My parents and they had also been friends for a VERY long time and the lost ring/found ring had never come up in conversation before this. They figured out that they had been stationed at 2 bases together after the ring was lost and another 2 bases after the ring was found. Always socialized with each other when stationed together, too.
The ring was finally returned to the owner -- and both couples told that story for many years after that! It was truly an amazing story and almost beyond being just a coincidence... I always loved hearing it!
