GEM KNOWLEDGE · LABORATORY NOTES
Glacierite
Blue Ice, also sold as Glacierite, reached the market as a purported natural discovery from Indonesia. Our testing raised a serious challenge to that description, and the vendor later confirmed to Soul Body Gems that the material was not naturally formed.
Laboratory finding: The sample was dominated by aluminum with lesser sodium and magnesium; some areas contained calcium and silicon. The dark blue region contained iron, nickel, and minor zinc and zirconium. A bubble-like void was observed. Preliminary X-ray diffraction suggested a material similar to dawsonite, but the researcher said more work was needed and described the first impression as man-made.
What “slag” means here: The material is commonly described in market discussions as industrial slag. The report and vendor confirmation support calling this piece manufactured rather than a naturally crystallized mineral, but the precise industrial source and process were not established by the report. We do not present the preliminary dawsonite resemblance as a final identification.
Report detail: Completed March 24, 2023. This document prints sample ID 92955, also printed on a different Tanzania feldspar report; the specimen photographs, dates, and findings distinguish the documents. Both are reproduced as supplied.

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 specimen is very interesting (Fig. 1). The bulk composition is dominated by aluminum with lesser sodium and magnesium (Figs. 2-4). Locally, calcium and silicon are present (Figs. 5 and 6). The dark blue colored area contains iron, nickel, and minor zinc and zirconium (Table 1). A first attempt with X-ray diffraction suggests a material similar to dawsonite which is a sodium aluminum hydroxyl carbonate. There is some more work needed an this specimen but the first impression is that it is man-made.
