Fluorescent Minerals found at Sterling Hill Mines, New Jersey! Orange - Wollastonite Green- Willemite
Crystals, guys. More natural patterns.
The top image is a Lichtenberg figure, which is created by discharging an electric current into an acrylic pane, which is then decomposed, showing the pattern of current discharge.
[ That’s why it looks like lightning. Same concept, different medium. ]
It’s a dendritic pattern, showing fractal symmetry and self-similarity at all levels.
The silver crystals to the left are native silver, which grows in dendritic patterns. Similar patterns may be found in gold, copper, and other metals.
…Bismuth, to the right, is a little unique. Its crystals are still self-similar, though, and look about ten times as cool, in my opinion.
