When I was in fourth grade, Gail Bayarin and I got best friend hearts. She had the “Be Fri” side, and I had “St Nds.” Not long after getting our necklaces, we got into a fight, about what I can’t remember. But I do remember that I took off the necklace while Gail was watching, and she responded by doing the same. (Preteens are gangster.) Turns out, had we been a bit older—and had the charms been real gold and the internet existed in the 1980s—we might have made a pretty penny from our tarnished friendship on resale sites like The RealReal, Vestiaire and other luxury-secondhand-goods shops, which feature a wide array of previously owned sacred jewels. If you’re looking for a deal and the thought of someone else’s misery doesn’t bum you out, feast your eyes on these babies!
