This piece features two ball-like aggregates of sharp thomsonite crystals, associated with stilbite crystals and tiny sparkling heulandite crystals. (This is thomsonite-Ca.) The thomsonite crystals are easily seen projecting into the protected space in the middle of the specimen – they are sharp. In excellent condition – no damage – the thomsonite balls look uneven because they grew with interruptions from the other zeolite minerals. This specimen is from the small 2020 find.
