Hardin County, Cave-In-Rock District, Illinois
A nice spray of strontianite crystals shows cluster of long, tapered crystals in spray like groupings. They are covered with a micro dusting of a slightly darker mineral, giving a nice contrast to the piece. This fluoresces strongly in white and yellow colors in both LW and SW UV light. This is from old stock and represents a rarer locality for this mineral.
