Laavasta

Laavasta is a fictional mineral introduced in speculative fiction and tabletop role-playing contexts. It is not a real mineral, and its properties vary by work, but it is commonly imagined as originating in volcanic settings and valued for its visual appeal and unusual traits.

The name is often linked to laava, the Finnish word for lava, with the -sta suffix implying origin or essence. In some texts, laavasta is described as crystallizing in rapid cooling or being formed in volatile gas pockets near eruptive vents.

Physically, laavasta is typically described as glassy and iridescent, sometimes translucent with shifting colors. It is usually portrayed as hard and heat resistant, able to survive near-field temperatures that would deform ordinary rocks.

In-fiction formation scenarios vary: rapid cooling of lava in underground conduits; crystallization within basalt nodules; or growth in hydrothermal fracture systems. Some depictions grant it faint luminescence or a subtle magnetic or energetic signature.

Uses in fiction range from energy storage and focus crystals to tempered alloys and ceremonial jewelry. Its imagined properties—stability under heat, light emission, and aesthetic appeal—make laavasta a versatile plot device in stories and games.

The term appears across fan wikis, game manuals, and short stories, but there is no single canonical description. Readers encounter different variants depending on the author or setting.
