Holdenite is a rare manganese zinc arsenate silicate mineral named after wealthy collector Albert F. Holden (1866-1913), who donated his collection and estate which established a large endowment at the Harvard Mineralogical Museum for specimen acquisitions (Palache & Shannon, 1927). Later study by Moore & Araki (1977) established the currently accepted formula. Holdenite here forms fine granular pink-purple masses on willemite-franklinite ore. Holdenite is an extreme rarity unique to Franklin-Sterling Hill.
This specimen comes from the Bob Trimingham collection, a collector from Livermore, California. His detailed collection card indicates purchase from Nature's Treasures (Dwight Weber) in 1978.
