Quartz Muscovite (Brazil) Meaning, Metaphysical Energy & Geology

A specimen from a small Brazilian pocket find, examined for its dark prismatic crystals and inclusions in quartz.

Finding: Sample 9274, specimen 2, completed June 11, 2021, is quartz with dark dravite–schorl-series tourmaline and inclusions of muscovite, potassium feldspar and fluid. The quartz had trace titanium and iron in the measured area.

The report suggests a quartz vein related to a granitic pegmatite or a pegmatite influenced by magnesium-bearing surrounding rock. “Quartz Muscovite” is a practical market label for this material, but muscovite is not the only included mineral. A separate product photograph can be added later; the original report contains the specimen image.

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.

Summary of findings: This is a beautiful specimen: (Fig. 1). Most noticeable are the dark prismatic crystals on the quartz (Figs. 2-4 and Fig. 9). Besides lots of fluid inclusions, there are also inclusions of potassium feldspar (Figs. 5 and 6 and Fig. 9) and muscovite (Figs. 7-9). The quartz itself only contains traces of titanium (170 ppm) and iron (110 ppm). Specimens like this are likely found in quartz veins closely associated with granitic pegmatites or in pegmatites that have assimilated sufficient amounts of mafic country rock which would bring up the magnesium. Phlogopite is a mineral more typical for metamorphic rocks that had a provenance of a mafic igneous rock.
