Berylliaa

Berylliaa is a fictional mineral described in speculative geology and worldbuilding. The name draws on the real beryllium-bearing mineral family and follows common naming conventions used for imagined minerals.

Occurrence and formation

In fictional accounts, berylliaa is said to form in high‑temperature hydrothermal systems and pegmatites, where beryllium‑rich fluids interact with aluminum‑silicate host rocks. Crystals are described as hexagonal prismatic and are often found in radiating aggregates within other minerals.

Composition and properties

Berylliaa is portrayed as a beryllium‑rich aluminosilicate with trace impurities such as rare‑earth elements that influence color. Reported color ranges include colorless, blue‑green, and golden‑yellow. The mineral is described as having a vitreous to pearly luster, with a Mohs hardness around 7–8. Its refractive index and birefringence are depicted as high, contributing to strong dispersion in gemstones.

Uses and significance

In-world, berylliaa is valued as a gemstone for jewelry and is occasionally depicted as a material for fictional energy devices or advanced optics. Its rarity and association with other beryllium‑bearing minerals contribute to its economic and symbolic importance in storytelling.

Notes

Because berylliaa is a fictional concept, no real specimens exist. It may be used as a plot element in science fiction, fantasy, or educational worldbuilding, often alongside real minerals such as beryl and quartz. See also: Beryl; Aluminosilicate; Hydrothermal processes.
