bomlanak

Bomlanak is a fictional mineral that appears in speculative fiction and world-building texts. Described as a translucent, iridescent silicate, bomlanak ranges in color from deep cobalt to teal and exhibits a pearly luster. In the narratives, it forms in high-grade metamorphic rocks where hydrothermal fluids alter silicate minerals, often in tectonically active regions.

Etymology: The name is said to derive from the imagined Langari language, with bomla meaning light and nak a common mineral-suffix, signaling its mineral status.

Discovery and occurrence: In the fictional account, bomlanak was first identified in the Kethar Basin by researchers who noted its distinctive optical properties and inclusions of copper-bearing minerals. It typically occurs as prismatic to tabular crystals in vein networks.

Properties: Bomlanak is described as relatively hard for a silicate, with a hardness on the Mohs scale around 6.5 to 7. Its refractive index yields strong iridescence, especially when cut as a gemstone. Specific gravity is reported in the mid-range for silicates. It often shows pleochroism, changing color under different crystal orientations.

Uses and cultural significance: In the stories, bomlanak is valued as a gemstone and a source of light energy for ancient devices. It also features in folklore as a symbol of insight and protection, and is depicted in jewelry, carvings, and ceremonial items.
