Heading to Westfield Montgomery Mall this fall: Alex and Ani, the white-hot jewelry chain known for its stackable bangle charm bracelets and its mission to “spread positive energy.” Made in the U.S. from recycled materials, with prices starting at $28, the eco-conscious line also includes fan jewelry for sports teams, the armed forces, various universities and the Disney parks. Alex & Ani will replace the mall’s Things Remembered store, which departed earlier this month.
