A very interesting fluorite, SHOT through with inclusions of stibnite that are wholly contained WIHTIN the crystal, and not present on the quartz matrix itself?! 2.8 x 2 x 2 cm crystal. NOTE: NOT FROM THE ZINN COLLECTION (but it got mixed in with them and photo'd, so I left it for the update). The stibnite was confirmed by xray at the university of boudler in colorado, I am told. 5.8 x 3.5 x 2.5 cm
