Description

Basalt matrix with multiple amygdales lined with clusters of small bladed thomsonite crystals. The thomsonite crystals are unusual in that some are the normal grey or colouress but some have a nice pink/red colour and others a pale orange colour. This variation is due to impurities in the amygdales. The colours are completely stable as I collected this specimen 13 years ago and the colours have not changed since the day I first found the specimen.
