Where to Find Fluorite in Utah
Utah fluorite shows up in two main settings. Spor Mountain in Juab County, the world's primary beryllium source, produces lavender-purple fluorite octahedrons in the topaz-bearing rhyolite, often with bertrandite and red beryl associations. Indian Peaks in Beaver County yields green and purple fluorite in rhyolite vugs. Smaller showings line the cuts in Cottonwood Canyon east of Salt Lake City, with cubic green and colorless crystals in carbonate matrix. The Lost Sheep and Lost Wonder claims at Spor Mountain are the standard collecting ground when access is open. Surface fluorite weathers cleaner here than in wetter states.

Standout fluorite spots in Utah
Hand-picked from the full list below, with the reason each one earns a trip.
Dugway Range
Juab County County
The Dugway Geode Beds are one of Utah's clearest geology-to-specimen localities: Miocene rhyolite cavities were eroded by Lake Bonneville and redeposited as diggable geodes in lake sediments. BLM lists the beds as a rockhounding hotspot, and UGS notes that the geodes commonly contain clear, purple, or pink quartz.
Spor Mountain
Juab County County
Spor Mountain stands out because its topaz-rhyolite-related deposits made it the world's premier beryllium district and Utah's largest fluorite producer. Mindat documents bertrandite, fluorite, chalcedony, opal, carnotite, hematite, magnetite, pyrite, quartz, and topaz across the district, which makes it more than a single-specimen stop.
Topaz Dome Quarry
Juab County County
Topaz Mountain is Utah's defining gem locality, where amber topaz crystals formed in cavities of the Topaz Mountain Rhyolite and commonly bleach colorless in sunlight. The BLM identifies the area as a public rockhound recreation site, while the Utah Geological Survey documents topaz, red beryl, amethyst, garnet, bixbyite, opal, and hematite in the same volcanic field.
Marysville
Piute County County
Marysvale earns a top spot for small but well-formed crystals in rhyolite cavities, especially bixbyite, amethyst, and reported rutile or pseudobrookite. UGS describes the occurrence as BLM public land in a mid-Tertiary volcanic field, and Mindat records the same locality north of Marysvale with bixbyite, amethyst, pseudobrookite, and rutile.
