Physical properties
Hardness of 6-7 on Mohs scale, intergrown quartz and alkali feldspar crystals showing cuneiform or runic patterns, vitreous to dull luster.
Formation & geological history
Formed through the simultaneous crystallization of quartz and feldspar in granitic pegmatites during the late stages of magma cooling.
Uses & applications
Used as an ornamental stone, in lapidary arts for cabochons, and as a specimen for geological collections.
Geological facts
The mineral intergrowths naturally resemble ancient cuneiform writing or rune scripts, which gives the rock its unique name.
Field identification & locations
Easily identified by its distinct graphic patterns of dark quartz embedded within lighter feldspar; found globally in pegmatite-rich regions.
