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 above, with the reason each one earns a trip.
Dugway Range
Juab 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.
Spor Mountain
Juab 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.
Topaz Dome Quarry
Juab 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.
Marysville
Piute County
Marysvale earns a top spot for small but well-formed crystals in rhyolite cavities, especially bixbyite, amethyst, and reported rutile or pseudobrookite.
