Looking for something to comfort us when someone we loved passes away. I wanted something special since , my mother was just that "Special"

Like they did so many years ago, a lock of hair was a memento of someone who died. This made perfect sense to me since it holds DNA.
So I really wanted to find something to hold a precious lock of hair I have of my mother's, who passed away in Oct. I looked around and couldn't find anything that was special for me.
I started looking for something in my drawers, and there it was, an old watch of my mothers. I had to think what could I due, so I had it set at the time she died, had her hair place within the fittings, the garnet is her birthstone and the shape represents the tears we have shed. I found a cord similar to what it would have been worn on, so I now can wear it as a pendent and have her near.

Some would say this is out of the box thinking, what have you done to remember someone you loved who passed away?
