Perched aesthetically on a contrasting matrix of silvery galena and stark white calcite, is a cluster of intergrown, glassy and gemmy spinel-twinned crystals of fluorite. The fluorite cluster measures 6 cm across. Minor, white calcite crystals, to 0.75 cm in length are associated with the galena crystals that reach 0.5 cm across. This is an appealing combo specimen from Naica with lots of contrast. The aesthetic perch of the fluorite atop the stalk of matrix makes it unusual, as does the twinning so evident in the crystal itself. The crystal atop is remarkably in good shape and not repaired. This is a classic color, a pastel green hue, for the locale. Probably it was mined in the 1980s. This specimen was on loaned exhibit in the University of Arizona Museum for over a decade until my purchase of this collection in 2008. MUCH more gemmy in person! Comes with custom lucite base already made for the specimen.
