Flambeau Mine, near Ladysmith, Rusk County, Wisconsin, USA
81 x 69 x 43 mm
"Wheat sheave" shaped white Calcites to 32 x 16 mm, with pearly luster and light-red Hematite accents are perched on sparkly contrasting matrix of Calcite. Although there is some damage, this is a very rare and important specimen-one of only three Calcites found at the Flambeau Mine in Wisconsin, and the very best one found. It was collected by Casey Jones who sold it to F. John Barlow (#5972), and was later consigned to Casey upon dissolution of the Barlow collection. (Author: GneissWare)

This cluster of Calcite crystals consists of both elongated scalenahedrons and butterfly twins (to 44 mm) with a reddish tinge from Hematite inclusions that deepens in color towards the centers of the Calcite crystals forming nice Hematite phantoms. The Calcites also display distinct chatoyancy. Although it presents damage around the margins where it was removed, it is one of the only surviving specimens from what was reportedly a large, several meters long cave completely covered by such Calcite. It was given to me by Francisco Aguilera who worked at the Hercules Mine and actually collected it. Casey Jones and I met Francisco through the mine office because he spoke some English.
