This Australian material was marketed as Pink Petrified Wood. The examined specimen was not identified as petrified wood.

Finding: Sample 92905 (#5), completed April 18, 2022, was identified as a silica-rich, slightly silicified rhyolitic volcanic rock. A calcium-rich grain could be altered plagioclase or a zeolite; the report did not resolve its identity.

Why the market name matters: The report did not document wood anatomy or fossil replacement. It arrived at the laboratory under a “rhodonite” label, but the findings support neither rhodonite nor petrified wood in the examined area. Australia is the supplied locality.

Catalog note: The printed sample number 92905 also appears on separate beryl and ruby association reports. This entry is identified by its April 18 completion date and the pink Australian specimen; the reports are kept separate.

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.

  • Electron microscope image: This view shows small-scale regions selected for analysis. Its brightness contrast helps distinguish regions with different compositions; it is not a photograph of their natural colors. Numbered spots connect this view to the analyses listed in the report.

  • Elemental spectrum: The peaks record characteristic X-ray signals from elements in the analyzed spot or area. This is an analysis of that location, not automatically of the entire specimen. Any mineral identification or uncertainty named in the laboratory caption is retained below.

Potassium 3.61
Sodium 2.88

Summary of findings: This specimen (Fig. 1) is a silicified volcanic rock (Figs. 2-6 and Table 1. Silica is high (77 wt. % SiO2) but suggests a slightly silicified rhyolitic rock (Fig. 3), but the chemical signature is clear. A grain with high calcium (Fig. 4) is interesting and resembles a zeolite or a plagioclase. However, for a plagioclase it would indicate a more mafic rock which this material is not according to the high sodium and calcium (Table 1). The elevated barium is another indication for a felsic volcanic rock (Table 1).
