Description

Blueish-grey quartz crystals on a matrix of partially altered diabase, a grey-blue subvolcanic igneous rock. The 3 forms present in these quartz crystals are two equally developed positive and negative rhombohedrons, modified by slightly developed prism faces, giving the aspect of a hexagonal bipyramid. The blue coloration is likely to be due to aerinite and/or byssolite inclusions, both present at the deposit.

Self-collected Nov/28th/2010.
