- Ex. John S. White
I had never heard of Juddite before but was surprised to see a reddish mineral from India, associated with braunite, and so assumed it to be a manganese species. It turns out that it is indeed the manganese variety of arfvedsonite, by modern classification. the crystals are bright red, small but beautiful under a scope. The matrix is braunite: Braunite is very rare, and these are old specimens, from India. according to MINDAT: Juddite was named by Lewis Leigh Fermor in 1908 in honor of John Wesley Judd [February 18, 1840, March 3, 1916]. Judd was a field geologist and petrologist for the British Geological Survey and later professor of geology at the Imperial (Royal) College in London, England.
