Mystery Stone 9
A dendritic stone set in a ring, recorded as Mystery Stone 9 until its trade name is confirmed.
What the report found: The bulk of sample 1527 is granular quartz with hematite/goethite veining and dendrites, a thicker barite-bearing vein, minor titanium-bearing chlorite-group material, and kaolinite. The mounting tested as sterling silver.
The laboratory also used sample number 1527 on a different green teardrop report. These are distinct specimens and reports despite that duplicate number.

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.

Summary of findings: This is an interesting stone (Fig.1). The veining and dendritic parts are largely iron-rich, mainly hematite/goethite (Figs. 2 and 3). In a thicker vein barite has been noted (Figs. 2 and 4). The bulk is granular quartz (Figs. 5 and 6), something like a well-cemented siltstone. Minor amounts of a titanium-bearing chlorite group species (Figs. 5 and 7) and kaolinite (Figs. 5 and 8) were also found. The mounting is sterling silver with 3.5 wt. % copper (Fig. ).
