WHEN THE SUN HITS JUST RIGHT… FLUORITE FRIDAY MAGIC!

FOUR ABSOLUTE ILLINOIS BANGERS soaking up some sunshine at my desk!

There’s something magical about natural sunlight passing through these legendary fluorites from the Minerva No. 1 Mine in Cave-in-Rock, Illinois!

The colors are just RIDICULOUS!

Electric purples, icy blues, glowing amber-orange, golden yellows, and those insane internal color zones that seem to come alive when the light hits just right!

The transparency, glassy faces, sharp cubic formations, and incredible zoning make each of these beauties a miniature masterpiece of nature.

No fancy lighting needed… just a little sunshine and FOUR NEXT-LEVEL ILLINOIS TREASURES!

HAPPY FLUORITE FRIDAY!

Which of these four bangers is your favorite?
