Diamond Hill in Cumberland, Rhode Island, is a prominent white quartz hill whose sparkling surface gave it its colonial-era name. Rising 481 feet above sea level, it has long been a local landmark, with early colonial settlement nearby and skirmishes in the vicinity during King Philip's War. In the nineteenth century, quarrying and nearby copper mining brought industrial use to the area. In the twentieth century, it became a modest skiing destination as trails and lifts were added, but those operations eventually closed. Since Cumberland acquired the property in 1997, the hill has served mainly as a town park and recreation area, including trails, athletic fields, and community events.
