If you love fluorescent minerals, you will flip over this Willemite! Willemite is a zinc silicate mineral ( Zn 2SiO 4) and is highly fluorescent (green) under shortwave ultraviolet light, and also very bright under 365nm filtered longwave uv. This chunk is from the Franklin and Sterling mines in Franklin, NJ, and may or may not contain other fluorescent minerals such as calcite, sphalerite, hardonstonite. This makes a great addition to any long or shortwave mineral collection!

Illuminate your fluorescent mineral collection with the Willemite Fluorescent Chunk.

This zinc silicate mineral is the perfect addition to any long or shortwave collection and will instantly captivate with its vivid green under ultraviolet light.

Every chunk is between half an ounce and three ounces in size and comes from tailings piles from the Franklin and Sterling Mines in New Jersey.

As mining has stopped in these areas, this piece of history should be brought home while supplies last!

Not to mention, it’s sure to blow all your friends away with its mesmerizing beauty.
