Detailed Description

Sharp, lustrous crystals of analcime on dark golden stilbite. The analcime crystals are translucent to transparent, covering much of the stilbite. If you look for them, you can see there are small pink gmelinite crystals (pseudomorphs after chabazite) in association. In excellent condition, some incomplete crystals at the bottom, as displayed. Stands perfectly as photographed. Nice contrast and sparkle!

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.
