Purple Dumortierite Meaning, Metaphysical Energy & Geology

Polished purple dumortierite spheres and geometric carvings with white and violet patterns held in a hand.

Purple Indian material from a newer find, supplied as sugilite but identified by testing as dumortierite with quartz.

Sample: 10588 (#3) · Completed: April 25, 2024.

Identified: Dumortierite intimately intergrown with quartz, with minor zircon. It is not sugilite.

Locality: India, according to Soul Body Gems sourcing information.

The report suggests iron is responsible for the color. X-ray diffraction provides the decisive identification of dumortierite and quartz.

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.
Laboratory figure caption: Fig.2: Backscattered electron image of an area of the specimen in Fig. 1.
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.

Sample 10588 (#3), submitted by Soul Body Gems, completed April 25, 2024. An AMRAY 1830 SEM operated at 25 kV acceleration potential, 24 mm working distance, and 0 degrees sample tilt. The specimen was coated with 250 Å carbon; the attached XRF unit operated at 30 kV. A BRUKER D2-Phaser X-ray diffractometer operated at 35 kV and 10 mA.

Summary: High-aluminum silicate intimately intergrown with quartz. Iron is likely the cause of color. Minor zircon is present. Diffuse silicon-rich patches suggest intergrown quartz. X-ray diffraction identifies dumortierite with quartz, not sugilite. The report ends with the April 25, 2024 date and signature.

Additional tested specimen: purple palm stone

Sample 1233 · April 8, 2025

This additional specimen contains dumortierite, quartz and dravite (a tourmaline-group mineral), with minor titanium oxide, likely rutile. X-ray diffraction also confirmed dumortierite. This report complements the earlier tested specimen; it does not replace it.

Analytical Result Report

Sample id: 1233 purplish palm stone)

Submitted by: Soul Body Gems

Date completed: 4-8-2025

Operating conditions: An AMRAY 1830 SEM operated at 25 kV acceleration potential, 24 mm working distance, 0 degrees sample tilt, coated with 250 Å carbon, and also using the attached XRF unit operated at 30 kV.

A Bruker D2 Phaser X-ray diffractometer was also used in the study and operated at 30 kV and 10 mA.

Summary of findings: This is an unusual one! (Fig. 1). The palm stone is composed of dumortierite (Figs. 2 and 3), quartz (Figs. 2 and 4) and dravite (Figs. 5 and 7), a tourmaline group member and some minor titanium oxide, likely rutile (Figs. 5 and 6). The X-ray map (Fig. 8) gives an idea of the relative abundances, yellow is dumortierite, red is quartz, blue-green is dravite, black is rutile. Dumortierite was also confirmed by X-ray diffraction (Fig. 9).
