Natural Black Rutilated Quartz Bangle Bracelet 12mm Plate Gemstone

Natural Black Rutilated Quartz (Black Tourmalinated Quartz) is a distinct crystalline quartz variety defined by sharp, needle-like to prismatic inclusions of black tourmaline (schorl) naturally trapped inside a high-clarity quartz matrix. Formed deep within igneous pegmatites, hydrothermal fluids deposited silicate quartz around growing tourmaline crystals, encapsulating dark linear rods and random criss-cross needle networks within transparent to light smoky crystal structure.

Crafted into modern geometric bangle plate beads measuring approximately 12mm in length, this bracelet offers a comfortable 16-17cm wrist fit and displays crisp monochrome contrast. Each machine-cut plate is polished with comfortable beveled edges, allowing direct light transmission to highlight the internal black tourmaline inclusions against the clear quartz background.
