Feldomite

Feldomite is a valuable mineral which was heavily sought across the Alpha Quadrant in the 24th century.

In 2373, a large quantity of feldomite was discovered on Parsion III. The discovery led a large rush of corporations wanting to obtain the mineral, but a strike by the inhabitants of Parsion III meant that mining operations ceased. As a repercussion of this the Sepian Commodities Exchange went into chaos. (DS9 episode: "Business As Usual"; Star Trek CCG: Premiere)
