Stilbite (Green) Meaning, Metaphysical Energy & Geology

A green zeolite material offered as apophyllite, examined to determine the minerals responsible for its color.

Finding: The principal zeolite was identified as stilbite-(Ca), not apophyllite. Chlorite-group material contributes green color; hematite or altered chlorite contributes reddish-brown areas. The report also notes possible laumontite.

Report: Sample 9238, specimen 8, completed April 15, 2021. The analysis applies to this tested green specimen.

Understanding the report figures

Use this guide alongside the written findings and the original report transcript. It explains the purpose of each analytical figure and preserves the laboratory’s own figure labels. The interpretations apply to the tested specimen; signals alone do not establish the identity of every similar-looking stone.

Summary of findings: This sample (Fig. 1) is very interesting. It is mainly zeolite material; best match is a stilbite-(Ca) (Figs. 2 and 3). The green coloration is due to intimately intergrown chlorite group species (Figs. 4 and 5). The red -brown areas are due to an intergrowth of hematite, chlorite (likely oxidized chlorite) and stilbite-(Ca). The coloration is likely due to very tiny particles of hematite (Figs. 6-9) and oxidized chlorite rather than substitution of trivalent iron for aluminum in the stilbite structure since these reactions were taken place likely at low temperature which make it unlikely for the iron to have been mobile. It is possible, that some laumontite is present as well. A surprise came when the oval specimen as retrieved from the sample chamber, it had undergone partial dehydration (Figs. 1, 10, and 11).

The amounts of iron and lesser amounts on manganese are shown for the different colors in Table 1. Note that the iron content for the green and red colors is quite similar, it is likely the response to the oxidation state that yields red versus green colors
