Most of us have a little stash of jewels that haven’t seen the light of day in a generation or two. Maybe it’s a bejeweled brooch (don’t you just love that word?) from great-grandma, or your grandmother’s engagement ring whose day has come and gone. While jewelry takes longer to go out of style than, say, a dress, sometimes all that’s needed is an update to give those valuable gemstones a new life. And now that 21C Designs is on the scene, there’s no excuse! This tiny and private atelier offers exactly that. They’ll take your stash and work with you to design current, modern and oh-so-wearable works of gem art. The photos here will give you plenty of ideas, and as for me, I’m about to raid my jewelry box!. They design custom and bridal jewelry too, and keep your eye on their social media for occasional pop-ups featuring well-known designers. Open Friday and Saturday and by appointment. (They’ll even come to you!). Look for the cottage with the red door down the alley behind Angie Lu of Madison. 693 Boston Post Road www.21c-designs.com See the before and after pix here.
