This is a natural pegmatite decorator mineral specimen consisting of blocky muscovite mica crystals on albite matrix with a large area of black tourmaline embedded in the matrix. It is completely natural - just as it formed inside the earth! See a side view photo which better shows the black tourmaline in this natural decorator specimen of muscovite crystals on albite with tourmaline. There are over two dozen large intergrown muscovite mica crystals perched up on top of the albite with interesting hexagonal shapes.

Black Tourmaline Information

Mineral Specimen of Black Tourmaline Crystals in Quartz Matrix Black Tourmaline Crystals

Black Tourmaline is naturally pyroelectric, which means that a black tourmaline can produce an electrical charge when it is subjected to a change in temperature.

A piezoelectric current can also be generated when pressure is applied to a natural black tourmaline.

Metaphysical sources say that black tourmaline can defend against negative energies, and that it gives protection against negativity from other people as well as protection against negative energy from both electrical fields & magnetic fields.

Black tourmaline forms in many different geologic settings. It most often occurs in granite pegmatites. Tourmalines found in pegmatites are commonly black and they are associated with the feldspar varieties albite and microcline, along with quartz and muscovite. The light colored gem tourmalines are much more rare, usually occuring in pegmatite core zones with quartz (sometimes as smoky quartz crystals), cleavelandite mineral specimens, and muscovite (sometimes as the lithium rich variety lepidolite), and more rarely with amblygonite and spodumene (variety: kunzite).

Other geologic occurances for black tourmaline are: with quartz in hydrothermal veins where heated mineral bearing liquids or gases from deep igneous sources later cooled and crystallized along rock fractures, by boron metasomatism in contact and regionally metamorphosed rocks, and black tourmaline also forms in granites due to late stage alteration of micas and feldspars by boron containing fluids.

Tourmaline

Tourmaline is the name of a group of closely related minerals all having essentially the same crystal structure but varying considerably in chemical composition and in some of their physical properties. Tourmaline is best described as a very complex aluminum borosilicate.

There are eleven distinct tourmaline mineral species based on chemical composition: buergerite, chromdravite, dravite, elbaite, feruvite, foitite, liddicoatite, olenite, povondraite, schorl and uvite.

Tourmaline occurs in all colors! Commonly used names have been given to tourmalines of specific colors or color combinations such as indicolite for blue tourmaline, rubellite tourmaline for pink to red shades, and watermelon tourmaline for tourmalines showing concentric color zoning with pink-red cores surrounded by green. Because laboratory analysis is necessary to determine the precise chemical composition of a tourmaline, the generally preferred nomenclature today for tourmalines that have not been lab analysed is simply to use the color of the tourmaline specimen as a prefix followed by tourmaline as in green tourmaline.

The color in tourmaline is due to the presence of metal ions (Fe, Mn, Cr, V, Ti and Cu) in the tourmaline crystal structure. The color we see in tourmalines is the result of light being absorbed by these ions or by interactions between these ions.
