Some of my earliest memories of experimenting with personal style include acquiring a sizable collection of mood rings. Most were run-of-the-mill versions from museum gift shops, while the more trendy pieces came from every Y2K kid’s favorite mall mainstay, Claire’s – both complete with the color card for an accurate reading. Now, thanks to brands like Studs, Rhyden, and Astrid & Miyu, mood-reflecting jewelry has crept back into the accessories trend circuit some 15 years later, in part due to the resurgence of our never-ending affinity for nostalgia and playful kitsch.
