Stilbite, Analcime

Specimen # 102465
Mineral: Stilbite, Analcime
Location: Five Islands, Cumberland Co., Nova Scotia, Canada
Size: 4.1 x 2.8 x 2.7 cm


Detailed Description

A fan of golden-orange stilbite dotted with analcime crystals, and associated with pink of gmelinite (psedomorphs after chabazite). The gmelinite is “spongey”, with many small hollows. The stilbite fan is one of the niceset from the find, and as you can see from the photo it grew up against the gmelinite. This stilbite is among the top for colour, definition and size. The analcime crystals are sharp and have good lustre. In excellent condition, one small part of the fan is incomplete. This specimen must be mounted/supported to stand as it does in the ifrst photo – this is the orientation I prefer. It sits naturally as in the second photo. A super specimen from this 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.
