King of Prussia is now home to the second Hearts On Fire store in the United States. The diamond brand refers to its products as “The World’s Most Perfectly Cut Diamonds” due to the strict qualifications for its stones and because its diamonds get cut under 100x magnification, which is 10 times the industry standard. Jewelry is mounted in cases along the walls at eye level; sales consultants press a button on a remote to slide pieces out from underneath the glass when you see something you like. There’s a long community table for trying on and weighing options—along with interactive screens for flipping through look books—and the company’s in-house designer, Ilaria Lanzoni, introduces new styles of engagement rings and wedding bands (for him and her) every season. Prices begin around $2,500.
