Fluorite, Bethel Level Minerva #1 Mine, Ozark-Mahoning Company, Cave-in-Rock District, Southern Illinois, Mined c. 1995, Tolonen Collection, Miniature 2.3 x 3.8 x 4.0 cm, $450. Online 1/13 SOLD.


  • $ 45000

Zoned yellow and blue/purple with largest crystal to approx 3.0 cm on edge. There is no point of attachment as the specimen was loose in the pocket with recrystallized matrix. A number of these specimens were collected ca. 1994-1995 from very old workings that Minerva Oil Company had previously mined in the 1940s. The opportunity to document this era of mining was unprecedented and, on my part, exceptionally satisfying to fill in a gap in the history of the district. A very excellent miniature in great condition. Note the tetra hex modification on the cube in reflected light. Tolonen Collection. (Entered into Ross C. Lillie Collection database system as RCL2544).
