Magma Chalcedony Meaning, Metaphysical Energy & Geology

An Indonesian material that Soul Body Gems obtained as raw stone, introduced to clients, and submitted for testing in 2020. “Magma Chalcedony” is its market name.

Finding: Sample 9148 (#5), completed July 16, 2020, showed orange quartz/chalcedony colored by arsenic sulfides identified as orpiment/realgar. The gray zones were mainly quartz with minor aluminum, calcium and sodium; the researcher suggested former plagioclase phenocrysts in volcanic rock followed by hydrothermal alteration.

Our history: Soul Body Gems recalls being first to obtain the raw material, sell it, and commission testing for the market. This is our account of sourcing history; the analytical report establishes the specimen findings, not a market-wide priority claim.

Handling: The report detects arsenic-bearing minerals in the orange areas. Avoid making dust or ingesting material, and wash hands after handling rough pieces.

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.

Summary of findings: This is really interesting! The orange areas are essentially quartz (chalcedony) (Figs. 1,2,4, and 5) with orpiment/realgar as coloring agents! (Figs 1 and 3). The gray areas are mainly quartz with minor aluminum, calcium and sodium. It appears that there were initially phenocrysts of plagioclase present (Figs. 6 and 7), likely in a volcanic rock that than underwent hydrothermal overprinting and deposition of a low temperature arsenic sulfide assemblage. XRF analyses of the gray area only indicates 79 ppm arsenic as well as 8500ppm iron, 4500 ppm potassium, 1 et. % calcium and 0.7 wt. % sodium.

The orange areas contain 1650 ppm arsenic, 4600 ppm iron and 250 ppm calcium.
