Physical properties

Hardness 7 (Mohs), transparent to translucent base with needle-like inclusions, vitreous luster.

Formed in hydrothermal veins and pegmatites where silica and rutile crystallize together.

Commonly used in jewelry making, lapidary arts, and sought after by collectors for its unique inclusions.

The needle-like crystals inside the quartz are mostly rutile (titanium dioxide). The white needles are less common than golden or black ones.

Identified by the distinct needle-like inclusions within a quartz matrix. Found globally, notable deposits in Brazil and Madagascar.
