An interesting formation of fluorite- the largest piece looks like it is suspended atop the smaller fluorite crystals. The crystals have nice clarity and show purple and green tones when under direct light.
Measurements: ~ 3-1/2" long x 2" deep x 2-1/2" tall
Fluorite forms in a variety of colors and is transparent to translucent in clarity. The chemical composition of Fluorite is CaF2, (calcium & fluorine.) The variation in colors are due to trace amounts of other elements replacing the calcium during the crystalline formation.
Fluorite is used in a variety of industrial purposes and the overwhelming percentage of Fluorite in the United States was mined in Illinois and Kentucky. Illinois became the leading Fluorite producer in the early 1940's, but during the 1990's, 90% of the U.S. Fluorite was imported with Illinois remaining the last U.S. producer.
In Honor of Memorial Day, the Shop will be Closed, Monday, May 31st.
Hi folks! COVID cases are down! So, we are allowed to have up to 25 people in the shop &15 people in the museum. However, on Saturdays, the museum will remain closed and used only as an area for those waiting to shop.
(However, if we're slow we can sneak you down there, if you like.)
For now, face covering & use of hand sanitizer are still required when entering.
We ask that people please not come in with large groups, and please limit their stays to under an hour, so others can have the opportunity to also do their shopping.
If we have customers in line, waiting to get in, please be aware of that and be considerate.
Thanks again for your continued understanding & support!
