Sparkling analcime crystals on stilbite fans, and on an underlying bed of pink gmelinite. The analcime crystals are sharp and lustrous, translucent to transparent. The stilbite fans are well defined and the largest is doubly-terminated. The gmelinite crystals are etched pseudomorphs after chabazite, only really visible around the edges. In excellent condition and stands perfectly as photographed. A beautiful combination piece.
About These Stilbite-Analcime Specimens from Five Islands
Occasionally over the years, good finds have been made at Five Islands. These have included natrolite, analcime and stilbite, as well as the famous gmelinite-after-chabazite from Pinnacle Island. The specimens from this stilbite-analcime find are beautiful and distinctive, combining the two minerals.
The stilbite crystal groups can vary in hue from one specimen to the next, and it should be noted that the stilbite hues also vary under different sources of lighting – they are richest under halogen lights, less so under cool LED. As with all specimens on the website, the photographs are colour-balanced to daylight.
The vein-pocket zone where these specimens were collected was located in a precarious area, beneath an unstable-looking cliff face. Fortunately it was safe enough to excavate the zone, resulting in these beautiful specimens.
