Shenn Stones are dull red crystalline rocks in rough form, becoming a translucent reddish crystal of incredible beauty once refined and polished. The crystal is usually found in underground caverns in small, naturally-formed deposits. The perfect crystals are required as a focusing device in the production of a variety of advanced pieces of technology. The slightest trace of impurities will ruin the crystal's use as a focusing lens, rendering it useless.
Shenn Stones are a Planetary Resource that can be extracted from a Shenn Stone Mine, if they are listed on the Planet's Geological Survey (GEO), or converted from Raw Resources on any Planet using a Stripmining Complex.
