Krunti

Krunti is a fictional mineral described in worldbuilding and speculative geology literature. It is valued in the imagined worlds for its dense structure and distinctive blue-green, pearly iridescence, often appearing in vivid specimens used for ornamental and symbolic purposes.

In the fictional system, Krunti crystallizes in the monoclinic system, with prismatic to tabular crystals. It has a Mohs hardness of about 6.5 to 7 and a specific gravity near 3.4 to 3.8. The mineral displays a characteristic iridescence caused by thin-layer interference within its translucent matrix and may exhibit mild pleochroism, shifting hue slightly with viewing direction. Trace elements can impart variances in color, ranging from teal to deep sapphire.

Krunti forms in slow-crystallizing pegmatites associated with high-grade metamorphic assemblages. It is commonly found with feldspar, quartz, biotite, and rare phosphates. In the fictional geography, crustal uplift and fluid-rich conditions contribute to vein filling that concentrates Krunti crystals.

In the narratives, Krunti is mined in upland regions and used in jewelry, inlays, and decorative carvings. In some speculative technologies, its optical properties are described as enabling simple optics and signal applications.

Krunti figures in folklore as a stone of memory and night skies, linked to stars and the lake regions in several myths. It is often presented as a safeguard against misfortune when carved into talismans.
