There are a plethora of Mother’s Day gifts flooding the market, but perhaps one of the most sentimental is a locket. Designer Monica Rich Kosann knows this all too well, making the functional jewelry piece her signature. The NYC-based bauble maker’s roster now boasts over 130 locket styles in a variety of metals and shapes (circles, teardrops, flip-out renditions that hold four images), all with various degrees of embellishment. She explains that her driving question when designing a piece of jewelry is, “Can a woman give this piece to her daughter in 20 years?” Needless to say, it was hard to pick one of these modern heirlooms out for ourselves, but we managed to settle on a sterling silver “Burst” locket, studded with blue and white rose-cut sapphires.

Inside, I placed two images that evoke sweet motherhood memories. On the left: A picture of me kissing baby Diego, who was probably around 5 months old, dressed in a little bear suit gifted to him by the Freda Salvador ladies. I can still remember that day, Diego, my friend Joanna, and I heading to a party at florist Natalie Bowen‘s studio, dressing up in a vintage floral dress to match the theme and coming accessorized with my little bear.

On the right: A portrait of Diego and I taken for the launch of Mother in 2014, shot in my living room by my dear friend and frequent collaborator Maria del Rio. It’s so fun to tell Diego the little stories behind these pictures—which are about both him and me, but also the awesome community of women that constantly surrounds us—and of course, he loves opening and closing the locket. Over. And over. And over again!
