Wikipedia article

This article is about the current version of DF.
Note that some content may still need to be updated.

Star sapphires are extremely rare blue gems found in clusters of sapphires, which are themselves only found in clusters of bauxite - among the most valuable gems that can be found in Dwarf Fortress, on par with diamonds.

Like all precious and rare gems, they may also make up part of the walls of unusual volcanic walls.

In Real Life[edit]

The "star" pattern that this mineral is known for is caused by rutile (Titanium dioxide: TiO2) crystals that have impregnated the host corundum crystal. Star sapphires are only smoothed into cabochons, as cutting them with facets does not allow the star pattern to be seen.

Star sapphire cabochon.
