Description

You are bidding on a small miniature sample with a perfect cluster of hureaulite in a vug in spodumene from the Foote Mine. Associated with colorless to orange zoned crystals of mangangordonite/laueite, jahnsite group, rockbridgeite and struzite needles. Hureaulite of any quality at the Foote Mine is very rare, because usually it crystallizes in very tight vugs with no room to grow. This specimen is exceptional for the species at the mine.
