Let’s be real: diamond companies loved the left-hand tradition. In the 1940s, De Beers ran ads that said, "A diamond is forever—on your left hand, of course." They went all in on the left hand as the only correct spot.
Before that, many rings were simple bands or even thimbles. Yes, thimbles! Imagine proposing with a sewing tool. "Honey, I love you, but also, please mend my socks." Thankfully, we’ve upgraded.
But here’s the kicker: the left hand is also the non-dominant hand for most people. That means less wear and tear on the ring. Pure genius for a marketing team who didn’t want you complaining about scratches.
