An unusually sharp, pale violet, transparent, spinel-twinned Fluorite crystal from the Erongo Mountains displaying a LARGE bubble (fluid inclusion) that is easily visible and MOVES as you manipulate the crystal in your hand! The Fluorite crystal is flat due to its twinning by the spinel law, where the twin plane is parallel to large flat faces of the crystal. The crystal is nearly a centimeter thick, two-thirds complete and has good luster with the remarkable features being both the bubble and the twinning! This is a highly unusual, unique specimen from anywhere. Note that, because of the bubble inclusion, it is sensitive to pressure changes and should not be shipped by air. We can arrange for hand delivery of such a specimen. For those who "have it all" in fluorite, this is a rare inclusion indeed!
