Large Quartz Crystal with Tourmaline from Brazil

This impressive untreated quartz point from Brazil is a substantial and rare mineral specimen, weighing approximately 2.8 kg and measuring around 21 x 13 x 7 cm. What sets this piece apart is the natural presence of small green tourmaline crystals scattered across the surface of the quartz, along with elestial step formations—a unique combination that greatly enhances its visual and mineralogical appeal.

Elestial quartz, often referred to as "skeletal quartz," forms through complex growth patterns, resulting in stair-like or etched surfaces that reflect the dynamic geological processes during its formation. The addition of green tourmaline (a boron silicate mineral with variable chemistry) on the quartz matrix adds further scientific and aesthetic value. These tourmalines, nestled naturally on the quartz face, offer a beautiful contrast and rare pairing of minerals.

This specimen is completely untreated, preserving its authentic texture, luster, and mineralogical integrity. It hails from Brazil, one of the world’s most renowned localities for producing high-quality quartz and tourmaline specimens.
