| 14hhdm.o ((MOLYBDENITE, BIOTITE)), $25 MINIMUM BID, Alma, Park County, Colorado, 8 x 6 x 4 cm, Cabinet, | |
_small.jpg) | Historic specimen from the Colorado State Geological Survery, University of Colroado with a label taped to the bottom of the box tray. I believe the label may be glued to the box and then a thick protective rubbery tape attached over the label. I do not know how old but it is written in in rather than pen. One label is typed on an old typewriter. This one! These are Molybdenum specimens from Colorado. This one has two hexagonal crystals of Molybdenite on a Granitic matrix with small black lustrous Biotite crystals throughout the matrix |
