Kristalliset

Kristalliset is a term in a fictional science encyclopedia describing a class of crystalline minerals found in the Ardentis sector. The crystals are transparent to translucent prisms, capable of large, undistorted facets. The name reflects their crystal structure and light-transmitting properties, making them central to optics in the setting.

First described by field geologist Leena Sokolainen in 2149 during surveys around Haldis, Kristalliset was named for its glittering clarity. Later expeditions confirmed deposits in several volcanic-sedimentary sequences and established its presence across the Ardentis system.

Chemically, Kristalliset is silica-based, often approximating SiO2 with trace dopants such as titanium or aluminum that yield faint blue or violet tints. It crystallizes in the hexagonal system, has a Mohs hardness near 7, and a refractive index of about 1.75; under ultraviolet light it may show weak luminescence.

Formation occurs in high-temperature hydrothermal veins linked to granitic and rhyolitic magmatism. Kristalliset appears as clear to pale crystals in vein pockets, often beside quartz and tourmaline. Crystals may reach several centimeters and align with crystallographic directions that influence their optical properties.

Applications center on optics and photonics. Kristalliset is used to fabricate laser resonators, high-precision lenses, and crystal oscillators. Its rarity and mining difficulty affect price, while synthetic Kristalliset produced by controlled crystallization provides a parallel, tunable supply.

Variants include natural Kristalliset and synthetic analogues. Synthetic crystals can achieve higher clarity and tailored dopant profiles, enabling customized refractive indices and luminescence. Research focuses on improving growth methods, reducing defects, and ensuring provenance to address supply-chain concerns.
