Calcite Crystal Cluster with Marcasite Inclusions
Linwood Mine, Buffalo, Scott County, Iowa, USA
14.5 x 8 x 7 cm
At a recent show I found a table of Linwood Calcites of which I have not seen many, since I found some a few years ago. The overall quantity and quality of this batch was not as good as the earlier find. However, after looking through this batch I came across what every collector hopes to discover, i.e., a jewel among the many nice but not great specimens.
This wonderful specimen is a cluster of “absolutely pristine” modified rhombohedral, gemmy Calcite crystals with Marcasite inclusions. The largest crystal measures 8x6x5 cm with delicate striations and a golden phantom. See more at Hummingbird Minerals
