maksoitte

Maksoitte is a fictional mineral species described in speculative geology and worldbuilding contexts. In the setting, it is classified as a silicate mineral that forms under high-temperature metamorphic conditions and is notable for its green-to-teal color.

Maksoitte crystallizes in the monoclinic system and commonly forms prismatic crystals or granular masses. It has a Mohs hardness of 6.0 to 6.5 and a density of roughly 3.3 to 3.6 g/cm3. The mineral typically appears deep green to emerald in color, with a pale green streak and a vitreous to glassy luster. It is usually translucent to opaque and can show weak pleochroism in polarized light.

It forms during high-temperature metamorphism in dehydration zones associated with subduction, where fluids alter existing rocks. In the worldbuilding setting, maksoitte is found in the Valara Archipelago’s metamorphic belts, often alongside cordierite, garnet, and sillimanite.

Maksoitte is named after explorer Maksoi (fictional) who first described it in field notes, with the suffix -ite following traditional mineral-naming conventions.

Because of its color and hardness, maksoitte is sometimes cut into cabochons for jewelry or used as a decorative stone in architecture within the fictional world. In-world, its rarity limits use to high-value applications, and researchers in the setting explore synthetic routes and stability of analog materials.
