Nuummite (Finland) Meaning, Metaphysical Energy & Geology

Common search spellings include nuummite, nuumite, nummite and Nuummit. These spelling variants refer to the name; Greenland and Finland remain separate locality guides.

A Finnish nuummite specimen from Kainuanmäki, Paltamo, Kainuu, examined for Soul Body Gems. This locality material was introduced at the Tucson Gem Show in 2026, according to Soul Body Gems’ sourcing history.

Finding: Sample 1516, completed August 12, 2025, contains abundant labradorite and the amphiboles anthophyllite and gedrite. The researcher also found minor quartz, greenalite and probable ilmenite. Pyrite, pyrrhotite and a grain of chalcopyrite were observed in another area of the specimen.

Nuummite is a rock made of multiple minerals, not a single mineral species or a crystal form. The report concludes this specimen has the characteristic mineral assemblage seen in nuummite. Its optical shimmer arises from light interacting with fine internal structures; appearance can vary with composition and lighting.

Locality and scope: These observations are for the submitted Finnish specimen. They do not establish the composition of every material marketed as nuummite.

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 a very interesting specimen! A calcic plagioclase, labradorite is abundant (Figs. 2 and 3). It is associated by magnesium-iron silicates (Figs. 2 and 4). Minor iron titanium oxides, likely ilmenite, were also found (Figs. 2 and 5). X-ray diffraction was very useful in determining the species and anthophyllite and gedrite were seen to be abundant. A minor presence of quartz, greenalite, and other minerals was also noted. The sample prepared for the analysis did not reveal any of the sulfides, but they are indeed present in other areas of the specimen (Fig. 7). Pyrite, pyrrhotite and a grain of chalcopyrite were detected. Thus, the specimen has the typical minerals present that are seen in nuummite.

As an optical phenomenon, schiller/adularescence exists only in the presence of light; it is a product of the interaction between light and the internal microstructures of the mineral and not a property of the mineral itself. The effect is produced by alternating layers of two types at a scale near the wavelength of light (approximately 0.5 microns)– this leads to light scattering and interference, aided by the fact that the refractive indices of the two components differ slightly. In addition, if the minerals have an inherent color, this is added to the effect. And similar material from different locations will have somewhat differing compositions and this means that some variations in color and other properties are possible.

Labradorite occurs in mafic igneous rocks and is the feldspar variety most common in basalt and gabbro. The uncommon anorthosite bodies are composed almost entirely of high calcium plagioclase. It also is found in metamorphic amphibolites and as a detrital component of some sediments.

Nuummite is usually black in color and opaque. It consists of two amphiboles, gedrite and anthophyllite, which form exsolution lamellae that give the rock its typical iridescence. Other common minerals in the rock are pyrite, pyrrhotite and chalcopyrite, which form shimmering yellow bands in polished specimens.

In Greenland the rock was formed by two consecutive metamorphic overprints of an originally igneous rock. The intrusion took place in the Archean around 2800 million years ago and the metamorphic overprint was dated at 2700 and 2500 million years ago.

Nuummite has been identified from several locations: Greenland, Finland, Mauretania.

Nummite is not a mineral but a rock. There are no nuummite crystals!
