{"product_id":"calcite-on-quartz-with-sphalerite-and-bournonite","title":"CALCITE on QUARTZ  with SPHALERITE and  BOURNONITE","description":"An interesting combination of species and habits, this specimen is dominated by glassy white Calcite crystals up to around 2 cm tall, each capped with an overgrown broader Calcite crystal, so forming sceptre-like capped-crystals.  Dispersed amongst these are clusters of intergrown Bournonite crystals, some displaying the cog-wheel habit and all tarnished an iridescent steel-blue with flashes of bronze and red.  Sphalerite crystals also occur through the Calcite, usually of a translucent burnt toffee-orange.  A great specimen from the P?'bram District in Central Bohemian Region, Czech Republic.
