Fluorescent willemite from Franklin, USA. You can see a vein cutting across that does not have fluorescent minerals in it. ⚒️🧪

Rock specimen with mostly composed of small bright green crystals, with minor orange crystals, with a dark vein across it from top left to middle right.  It is under UV light in the dark on a glass shelf with a small 2 on it. At the Royal Ontario Museum.
