639 95ecjter ((BOURNONITE, MANGANOAN CALCITE)), Fluorescent, $50 MINIMUM BID, Pachapaqui, Ancash Department, Peru, 10.5 x 6.5 x 5.5 cm, Cabinet | |
Here is a combination of Bournonite cogwell crystals to 6 MM covering the matrix along with sheaves of light pink fluorescent Manganoan Calcite. The one small area of the Manganoan Calcite has a crack and is slightly loose but is trapped in place unless actually broken free. Specimen is attached to a clear plastic block stand with old blue min tack. This was in one of my cases at home for the past 10 plus years. |
