Friedelite (classic material)

Item Description

The Franklin / Sterling Hill area in New Jersey has produced hundreds of individual mineral species, and many of them are incredibly distinctive, as the assemblages don't resemble anything else in the world. This piece is a classic example of the uncommon manganese silicate, Friedelite, featuring a few saturated pink colored "veins" that are running through typical Franklinite/Calcite/Willemite ore matrix. With strong backlighting, small areas of the Friedelite will pass light. Old classic material from decades ago, and rarely available on the market today.
From the worldwide mineral collection of Albert Lewis Kidwell (January 1, 1919 - August 16, 2008). Al was a well-known mineral collector and research geologist with Carter Oil Company and later Exxon Oil Company in Houston, Texas. The phosphate species Kidwellite was named in his honor in 1974 ( https://www.mindat.org/photo-326405.html ).
