Clinochlore, Grossular, Diopside

Locality: Hunting Hill quarry (Rockville Crushed Stone Quarry; Travilah Quarry; Rockville Quarry; Bardon Stone Quarry; Aggregate Industries Quarry), Rockville, Montgomery Co., Maryland, USA

Orange translucent grossular garnets in Clinochlore on a matrix of massive chrome diopside. The Clinochlore crystals are nicely formed but are coated in some sort of white opaquish film. There are some white hydromagnesite crystals present as well. Specimen is much more attractive and a more intense green in person. Collected by J. Wingard 10-04 and in my personal collection. Specimen is approximately 6.5 cm across.
