Funny how that is the question of the day because I have a necklace from 1999, the year I graduated high school I wear from time time, actually more often than none. It was a graduation gift and it super clean to this day. I was just talking about the necklace last night with my kid. I even remember exactly when and where I purchased the necklace. Sadly the mall I bought it from is a ghost town of a mall now, but many memories from that place.
