Is anything in the world better than that free-as-a-bird, Friday-at-5 feeling? Sometimes all it takes is a hint of a captivity to make a sparrow sing all the sweeter. That bird and its flight to liberty are the basis for Erin Waxman’s ultra-modern line of sterling silver jewelry. Feeling particularly cooped up? Try the rib cage bracelet. Flighty more your style? The leaf earrings are just the thing to help you soar. While her designs borrow heavily from the industrial and may remind you of the bars (ahem, cubicle walls) that confine you on weekdays, they also capture nature in forms as delicate as a feather. Plus, Waxman shapes each bracelet, earring, and ring by hand, so you’ll always stand out from the office flock. And finally know why the caged bird sings. Available at Art Star Gallery & Boutique, 1030 North 2nd Street, suite 301 (215-238-1557 or artstarphilly.com).
