About HiddeniteHide

William E. Hidden
Named in 1881 by Joseph Lawrence Smith in honor of William Earl Hidden [February 16, 1853 Providence Rhode Island, USA - June 12, 1918 Newark, New Jersey, USA], mining engineer, mineral collector, and mineral dealer. Hidden was co-namer of mackintoshite in 1893. The town of Hiddenite was named after the mineral variety in 1913.
A variety of Spodumene

Hiddenite was not originally defined by Kunz as has been sometimes claimed. Smith (1881) did state: "I have employed all the necessary care in examining for chromium, but have found no indication of its presence." Smith tried to verify the presence of vanadium, but could only conclude that his qualitative results would have been similar to either vanadium or chromium. Smith does indicate that his hiddenite varied from pale green to emerald green, "though the color is not so intense as in the finest variety of the latter gem."

Colorless or yellow spodumene should not be referred to as Hiddenite. Green spodumene that is photosensitive and not permanently color stable is not hiddenite.

The mineral variety hiddenite was originally described from Alexander Co., North Carolina, USA. The area where hiddenite was found was governed by county government and was then known as an informal settlement called "White Plains". The town name "Hiddenite" was not granted a charter until 1913, thirty years after the naming of the mineral variety hiddenite.
