This one looks like some sea monster climbing up! It is just bizarre, having the isolated stacked chain of sucecssively larger crystals perched upon matrix which seems apart. Massive, mirror bright, gray galena is the matrix for the two generations of fluorite. The first generation is gemmy, pastel green that is supplanted by gemmy, nearly colorless, stepped growth of cubes modified by octahedral faces. The largest of the latter generation measures 2.3 cm across. REALLY neat specimen, quite different from the crowd...
