A plate of beautiful, well-defined fans of golden stilbite with sparkling analcime crystals on top. The stilbite fans are distinct and the one in the centre is super. Around the edges of the specimen one can see small crystals of pink gmelinite (pseudomorphs after chabazite). In excellent condition, one incomplete fan at back left and otherwise even the margins are complete. Very nice colour and sparkle – for my taste, one of the nicest specimens of the find.

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.
