Willemite with fluorescence under UV light from Franklin Furnace, New Jersey, USA – 1 kg

This lot consists of 1 kg of Willemite from the world-famous deposits of Franklin Furnace in New Jersey, USA. In daylight, the pieces usually display rather inconspicuous colors, but under ultraviolet light they reveal the intense fluorescence that makes Franklin minerals so distinctive. The fluorescence is especially pronounced under shortwave UV light (SWUV). The material contains massive inclusions within a rich paragenesis typical of Franklin, including zincite and franklinite. Such lots are ideal for experimenting with UV lamps, for educational purposes, and as an addition to fluorescence collections.

Geology & origin

Willemite is a zinc silicate (Zn₂SiO₄) that occurs in Franklin Furnace together with zincite and franklinite in exceptionally rich assemblages. The deposits there were formed through a special geological process, where zinc-rich sediments were transformed by metamorphism and intrusions. Today, Franklin Furnace is regarded as one of the world’s most important localities for fluorescent minerals.
