Interesting Chlorite Phantom Quartz, with growth patterns clearly showing along with white crusting of included groundmass, possibly of dolomite. Deep green layering / masses within, plus some red/brown dots of moss-like chlorite. Terminations not great, but there are interesting self-healed aspects to the base, suggesting that this might have once been double terminated.
Size 3.5 x 2.75 x 1.5 cm
