Physical properties
Hardness of 6-7 on the Mohs scale, pink to brownish color with interlocking dark quartz cuneiform script patterns, vitreous luster, and no distinct cleavage.
Formation & geological history
Formed through the slow cooling of pegmatitic magma deep within the Earth's crust, allowing simultaneous crystallization of quartz and feldspar.
Uses & applications
Used primarily as an ornamental stone, in lapidary arts, and as a popular specimen for mineral collectors.
Geological facts
The name stems from the mineral intergrowths that visually resemble ancient cuneiform or graphic writing.
Field identification & locations
Easily identified by its distinctive runic or graphic dark markings set against a pink feldspar background; found globally in pegmatite veins.
