Chapter 2: Tools / Gems and Art Objects


Source Gamemastery Guide pg. 114
Gems are naturally occurring minerals, typically in a crystalline form, or, in a few cases, organic material such as amber, coral, and pearls. All but the largest gems weigh about half as much as a coin, so about 2,000 gems is 1 Bulk. Unworked gems are worth half the Price of a finished gem and can serve as the minimum raw materials necessary to Craft the finished gem. Lesser semiprecious stones are level 0 items, moderate and greater semiprecious stones are 1st‑level items, lesser and moderate precious stones are 4th‑level items that require expert proficiency to Craft, and greater precious stones are 7th-level items that require master proficiency to Craft.
