What's the most valuable thing you have ever fixed with glue?

My $500 Nikon digital SLR. The tooth that holds the lens on broke. Fortunately, I found the tooth in the bottom of the camera bag and used Krazy Glue.

A locket that my grandpa gave me before he passed away

Whatever it has been that I've glued its been with the strongest glue I've found on the market Gorilla Glue, it's waterproof and after 24 hour setup holds great! I've even used this in places with direct water spray.

A vase. It was left to me when my Aunt passed away. It was very valuable but since I had to repair it I know the value has gone down. It was worth about $2500.

My mother had a vase handed down through generations and us kids were playing ball inside the house and we broke it (and a foot through the ceiling too but that is another story) don't try it because glue does not work when the vase gets water in it, we know we found out the hard way lmao.
