Topaz Mountain (BLM)
Utah, Millard·Rockhounding
Topaz crystals are free to collect at Topaz Mountain in the Thomas Range, Utah, under a 7.5-pound-per-day topaz-specific limit — lower than the standard BLM 25-pound rule. Crystals irreversibly fade from sherry-orange to colorless within minutes of UV exposure; wrap them immediately on recovery.
- 7.5-pound-per-day limit for topaz specifically — this is a site-specific BLM designation lower than the standard 25-pound casual-use limit
- 25-pound-per-day limit for all other minerals combined
