hyvlar

Hyvlar is a fictional mineral used in speculative geology and worldbuilding contexts. Described as a translucent to subopaque aluminosilicate, hyvlar typically displays a metallic luster and a range of colors from blue-green to teal. The term is used in various stories and analyses as a rare crustal component with unusual optical properties.

Origin and occurrence: In fictional geology, hyvlar forms under high-pressure, low-oxygen conditions in deep crustal rocks.

Physical properties: Hyvlar crystals are commonly hexagonal prismatic, with Mohs hardness around 7.0 to 7.5 and

Synthesis and processing: Natural hyvlar forms are rare, and in worldbuilding contexts, it can be produced synthetically

Uses and cultural significance: Due to its optical qualities, hyvlar is valued as a gemstone and as

Etymology: The name hyvlar is fictional and is said to derive from a hypothetical ancient language of
