I have been searching for these exact earrings for almost seven years. I bought them as a birthday gift to myself from the Fogg Museum at Harvard, and they were my favorite earrings at the time. They disappeared around graduation/move-out; I actually cried because I'd lost them. I'd look through craft fairs, online shops, department stores, anything even similar to them, and I found nothing!
It struck me this morning to try finding an online version of the Fogg Museum gift shop, and I found this shop, still affiliated with Harvard's museum system. Who'd have thunk to look in the same place twice?
