This specimen features a nest of fine (small) natrolite crystals bounded by sharp lustrous analcime crystals. In addition, there is a calcite crystal in behind one side of the natrolite cluster, and there are small heulandite crystals, giving colour interest along with the green celadonite. There is a lot going on on this one. In excellent condition. Stands perfectly for display as photographed. This is a nice Blomidon piece.
