One of the nicest specimens from the find, this one has it all – a large stilbite fan of the top golden colour, sharp, lustrous analcime crystals perched about the specimen, and a pink gmelinite crystal (pseudomorph after chabazite) coated on two sides with sparkling analcime crystals. In excellent condition (small incomplete stilbite fans at the back edge where this was attached). A fantastic 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.
