we're Obsessed!

When the mercury rises, I put away the heavy hardware in my jewelry box—the gemmy cuffs, the major cocktail rings—and slip into pieces that expose a little skin. This elegant black diamond and gold ring by designer L Frank hits just the right spring note. The revealing vertebrate motif also makes me smile, because I think of that old Justin Timberlake standard, "Sexy Back."
