A group of golden stilbite crystal aggregates dotted with a few sparkling colourless analcime crystals. The stilbites are well-defined and fully terminated. The large fan at the left has particularly good golden orange colour. It has a small spot of chalky laumontite on it. The base is crystalline pink gmelinite. In excellent condition, no damage. A sweet specimen.
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.
