Corusca Gem

"They can slice through transparisteel like a laser goes through Sullustan jam."

- Lando Calrissian, on the strength of Corusca gems

Corusca gems were extremely rare and valuable crystals. They were produced by a combination of the extreme pressures present in the atmosphere of Yavin&mdash;pressures great enough to crush elements together&mdash;and the scraping of the liquified air of the planet against its metallic core. The sizes of Corusca gems increased with proximity to the core of Yavin. They could be found in no other place in the Galaxy.

Corusca gems were mostly valued for their beauty. The way that light reflected inside a Corusca gem would make it seem as if it had a furnace within it.

Corusca gems were some of the hardest objects known to the Galaxy, and had industrial as well as decorative applications. Large Corusca gems were mounted on drills and used for precision drilling when explosives could not be used.

Despite their well-known strength, Corusca gems had shatterpoints, miniscule points where multiple edges and facets would come together, forming an extremely weak spot. If delivered at exactly the right point, and exactly the right way, the slightest tap could cause the entire gem to crumble. This is comparable to the force power shatterpoint, which allowed users to see how situations and happenings were linked together in intricate and delicate forms.
