Hauyne
A sodalite-group specimen whose combined microscopy, elemental analysis, and X-ray diffraction indicate a likely mixture including haüyne.
Sample: 1504 (#2 cut sodalite). Completed: June 20, 2025.
Finding: Essentially a sodalite-group material, likely a mixed composition with haüyne, sodalite, and lazurite, plus intergrown gonnardite.
A mixed mineral composition
The analysis distinguishes two chemically different portions: one with little appreciable chlorine and another that is sulfur-rich. X-ray diffraction supports a sodalite-group identification. The report describes haüyne, sodalite, and lazurite as a likely mixed composition, rather than confirming a pure haüyne specimen.
Intergrown gonnardite, a zeolite, is considered likely to be the white material. The report includes a comparison photograph under UV-A, UV-B, and UV-C. The specimen measures approximately 1 cm at its maximum dimension.

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.

Analytical Result Report Sample id: 1504 (#2 cut sodalite) Submitted by: Soul Body Gems Date completed: 6-20-2025 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 Broker D2 Phaser was also used in the study and operated at 30 kV and 10 mA. Fig. 1: Photograph of the specimens. 1 cm maximum dimension. Right image under UV-A,B,C. Fig. 2: Backscattered electron image of an area of the specimen in Fig. 1. Fig. 3: Energy dispersive spectrum of spot 1 in Fig. 2. (sodalite group possibly) Fig. 4: Energy dispersive spectrum of spot 2 in Fig. 2. (sodalite group member) Fig. 5: X-ray diffraction scan of the material with potential matching pattern overlays. Summary of findings: This is an interesting specimen (Fig. 1). It is composed of two distinct species. One is likely a member of the sodalite group (Figs. 2 and 3) but does not contain an appreciable amount of chlorine. The other portion is sulfur-rich and shows a composition compatible with sodalite group members. The X-ray diffraction scan confirms that it is essentially a sodalite group member, likely a mixed composition with haüyne, sodalite, lazurite plus intergrown gonnardite, a zeolite, that is likely the white material.
