Diamond is a ghost town in eastern Juab County, Utah, United States.

[2] The site of the former community is along the Diamond Gulch on the western slopes of the East Tintic Mountains, northwest of Sunrise Peak,[3] just east of the Tintic Valley, and about 5 miles (8.0 km) south of Eureka.

[6] The community received its name from the quartz crystals found in the area that were originally thought to be diamonds.

[8] Soon after a post office was established[9] and saloons, stores, and even a school was built.

[10] The population eventually grew to about 900, but after water was struck in the nearby mines the last residents moved away in 1890 and the town was abandoned.
