Three intergrown, or twinned, cubo-octahedral, glassy, emerald-green Fluorite crystals form an 'island', or mountain range as it is dominantly their one half (a pyramid with a truncated cubic top face) which is present - the back of the crystals being absent from where they grew upon Pyritic matrix. The three crystals' top faces are parallel, but staggered at different heights, like steps. Transparent, but with some inclusions, the Fluorite crystals are quite gemmy and their upper crystal faces are sharp and in great condition. One pyramidal side to the crystals is rough with large inclusions of poorly formed, rounded, gun-metal grey Geocronite and further crystals of this very rare lead sulphosalt species are intergrown with golden Pyrite crystals across the base of the Fluorite crystals where they were attached to matrix. A very fine 'individual' crystal (or group of twins) of this new 'classic' Fluorite from Peru with its typical association with well-crystallized small Pyrites, and rarer Geocronite.
