tutarszlk

Tutarszlk is a fictional mineral described in encyclopedic exercises and speculative world-building. In the imagined geology, tutarszlk is a complex aluminosilicate phosphate that forms in pegmatitic veins of continental crust and displays a deep azure color when freshly cut. Crystals are typically prismatic and can reach several centimeters in length, with a vitreous to resinous luster and a translucence range from transparent to semi-transparent. On the Mohs scale, its hardness is stated as about 6.5, and it is noted for weak to moderate pleochroism.

The name tutarszlk is said to derive from local dialects within the fictional region where it was first described, with etymological roots commonly interpreted as related to brightness and crystal quality. In the imagined classification, it is placed in a hypothetical group of minerals featuring trace rare earth elements, which are invoked to explain subtle luminescence under ultraviolet light and minor electro-optical effects. The proposed composition describes a layered framework that blends silicate and phosphate units with alkali and alkaline earth cations, though exact formulations vary in different narrative sources.

Occurrences are postulated in pegmatitic dikes of the fictional Valen Ridge region, where tutarszlk is said to appear alongside quartz, spodumene, and beryl. Because tutarszlk is not a real mineral, there is no genuine mining data or supply chain. In narrative contexts, it is sometimes used as a decorative gemstone or as a material of interest for speculative electronics due to its purported luminescent and electro-optical traits, and it is often employed to illustrate mineral description and classification without reference to real-world specimens.
