Larrel

Larrel is a fictional mineral described in speculative fiction and world-building discussions. It is not a real mineral or element recognized by geoscience, and references to larrel in scholarly literature are fictional or derived from later fan works.

In common fictional depictions, larrel is a translucent to iridescent gemstone with a glassy to waxy luster. Writers often describe it as forming in hydrothermal veins and in crystallized interiors of volcanic rocks. Its color ranges from pale blue to emerald green, and it is frequently attributed with a faint, natural glow that intensifies under ultraviolet or low ambient light.

According to various settings, larrel has a high refractive index and notable birefringence, leading to striking play of color when cut as a gemstone. Its crystals are typically described as elongated prisms or tabular forms, and some authors attribute a soft, musical resonance when struck. The material is often portrayed as difficult to synthesize, contributing to its desirability among collectors and researchers within those stories.

Formation and occurrence: In many narratives, larrel forms in high-temperature hydrothermal systems or magmatic chambers within secluded mountain belts or volcanic arcs. It is depicted as rare, historically valued by artisans and scholars, and sometimes guarded or mined by guilds or clans.

Uses and cultural role: In jewelry and ornamental objects, larrel is prized for its color and glow. In science fiction settings, it is sometimes proposed as a medium for energy storage or as a photonic crystal due to its luminescent properties.

Etymology: The name larrel is a constructed term appearing in multiple world-building communities; its earliest published usage is unclear and likely derived independently in various branches of fan fiction and gaming lore.
