Bixbyite
In Utah, bixbyite commonly occurs in cavities within topaz-bearing rhyolite, often found alongside red beryl and pseudobrookite, It’s considered one of the finest oxide minerals from the United States.
Discovered: Late 1800s, first described 1897. It is named after: Maynard Bixby (1853–1935), a prominent Utah prospector and mineral collector, hense the pronounciantion of "bixby-ite"
Maynard Bixby worked extensively in the Thomas Range of Utah and also discovered red beryl, originally called bixbite in his honor. Because “bixbite” and “bixbyite” sounded too similar, the name bixbite was later abandoned to avoid confusion—red beryl is now officially “red beryl.”
Bixbyite has no major industrial use due to its rarity, but it is highly prized by mineral collectors.
