Sajandite

Sajandite is a fictional mineral species that appears in science fiction and fantasy settings. It is commonly described as a blue-green, translucent silicate with a glassy to vitreous luster and a hexagonal crystal habit. Because it is a media-created element, there is no single, authoritative chemical description; sources vary in their proposed compositions, often presenting sajandite as an aluminous silicate with trace copper and iron impurities. Typical hardness values in fiction place sajandite around 6.5 to 7 on the Mohs scale, with a specific gravity in the low to mid range for silicate minerals.

In narrative contexts, sajandite crystals are said to form in hydrothermal veins and within basaltic lava flows in a fictional region called Sajand. They are usually rare and highly valued for their color, clarity, and optical effects, which can include faint chatoyancy or a subtle opalescent sheen under certain lighting. The mineral’s appearance, combined with its supposed spectral properties, often makes it a sought-after material for jewelry and ceremonial objects within stories.

Etymology and naming in fictional works typically attribute sajandite to the imagined region of Sajand, invoking ancient crafts and mystique associated with the landscape. The mineral is used in various ways across different settings, including as a gemstone, a focus of energy or magic, or a component in speculative technologies within the world where it appears.
