“2.3 x 1.2 x 0.9 cm This piece comes from the collection of noted Colorado geologist Allen Heyl, for whom the species Aheylite was named. It features one of the most distinctive and well known minerals from the famous phosphate producing Tip Top Mine, Montgomeryite. The species is named after the famous mineralogist Arthur Montgomery. Arguably the finest color Montgomeryite crystals are the fiery orange-red monoclinic blades from the Tip Top Mine, as seen on this specimen. In addition, there are small white crystals of the rare phosphate Fairfieldite and trigonal crystals of another rare and desirable phosphate, Whitlockite. ”
