A SUPEB cluster of blocky, striated, moderately lustrous, black manganbabingtonite crystals aesthetically set on a very complimentary matrix of translucent balls of bladed, sea-green prehnite. This outstanding combination piece is from recent finds at the Ganzhizhou Mine of China. Manganbabingtonite is an ULTRA-RARE silicate and this is a really good one. The manganbabingtonites are damage-free.
