The Franklin and Sterling Mines are some of the most famous mineral localities in the world!

Illuminate your fluorescent mineral collection with the chunk of Willemite and Calcite. This material is highly fluorescent under shortwave UV light, and very bright under 365nm filtered longwave UV light. It is sourced from the tailing piles at these famous mines, so you can be sure that you're getting a great piece of history!

These will blow your friends away when you light them up with the Convoy C8!

Willemite and Calcite is a zinc silicate mineral ( Zn 2SiO 4) and a minor ore of zinc. It is highly fluorescent (green and red) under shortwave ultraviolet light. ..and also very bright (green with pink) under 365nm filtered longwave UV.  Pictures are taken with both longwave 365nm (Convoy C8) and under shortwave 255nm 35 watt Way Too Cool.

These are chunks or cut pieces all from tailings piles, from the Franklin and Sterling mines in Franklin New Jersey.  All pieces are between half an ounce and 3 ounces in size. These make a great addition to any long or shortwave mineral collection. 

Some pieces may or may not contain other fluorescent minerals such as Calcite, Sphalerite, Hardonstonite and others. 

Get your piece of history from the Franklin mines before they are all gone. As mining has stopped in Franklin so no new material is being dug.

Great Sample

It's been great fun to share with our family. The samples helped to clearly show that finding them would be easy.
Much better than sitting in front of a screen! Everyone is excited about rock hounding ... a fun way to learn about our state and learn geology at the same time.
