A beautiful cluster of unusual blue prehnite, this is a very 3-dimensional group of intergrown crystals – a little flower-like, overall. The individual crystals are well-defined with good lustre. In excellent condition, a couple of incomplete crystals at the periphery.
The hue of this specimen changes dramatically under different light sources. Under halogen it is a cold, light blue, and under LED and daylight, it has more depth of colour and more warmth.
This is a great blue prehnite!
