Many years ago I gave a pearl baby ring to a boyfriend of mine in high school to wear on a chain around his neck. He gave me his class ring to wear, as well.
At the time, when we exchanged rings, my grandmother, who gave it to me when I was born, had recently past away. Unfortunately, the chain broke and the ring was lost while my boyfriend was at work. Though he tried to find the ring for me, it was never recovered. After searching for a couple days, he finally admitted to loosing it and we were both sad because of the sentimental value. As hard as it was, when we ended our relationship, I returned his ring.
