Where to Find Quartz in Utah
Utah is best known for one quartz-family target: Topaz Mountain rhyolite crystals. The cavities at Topaz Mountain in Juab County yield clear and smoky quartz alongside the topaz, the bixbyite, and the red beryl that put the area on the world map. South of there, the Dugway geode beds in the Thomas Range produce hollow chalcedony nodules with clear quartz interiors. Pegmatites in the Mineral Mountains near Milford add smoky quartz on feldspar. Surface float of rock crystal turns up in dry washes through the Wah Wah Mountains and the western desert, often etched and frosted from desert exposure.

Standout quartz spots in Utah
Hand-picked from the full list below, with the reason each one earns a trip.
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.
