Willemite var. Troostite (Historic specimen)
Franklin/ Sterling Hill
New Jersey, United States
4.7 x 3.2 x 2.7 CM (miniature)
price: $480
new year 2021

Two crystals of Mn rich Willemite (Troostite) in Calcite collected by Wallace Gould Levison in 1889. While the Troostite variety of Willemite is only known from the Franklin and Sterling mines, this specimen was actually collected in Jersey City, New Jersey at the Zinc Works there. It was found in a load of Zinc ore transported from Franklin to the smelter there, so this is unique, being probably the only Troostite that was not collected from Franklin. The Willemite crystals are a brick red color, well-formed though with typical slightly crude edges up to 3.1 CM. We will include a photocopy of the handwritten ledger from the Levison collection. Levison was a prolific 19th century collector located in Brooklyn who became very interested in the fluorescent minerals of Franklin. He invented and patented a specimen viewing box for shortwave UV light in 1909. A nice specimen with a great provenance.
