What Someone with Mineral Lore at 51% Knows People in Glorantha have as much trouble telling gems apart as people on Earth do. They may have more, because the shape of a stone gives no information about it. With some exceptions, any stone could have its shape because a sorceror formed it that way. Sorcerors can also mold a mottled or banded stone like clay until it has a consistent color. Sorcerors or simple craftsmen can change a stone's texture. This leaves color, transparency, toughness, and fragility as the main distinguishing characteristics. Glass is the great unknown. It can be flecked, banded, layered, milky, silky or catseye. It can be transparent or translucent, or opaque if a dark color. Notes: s = solid (assume all gems are solid unless an m or b note appears) f = flecked m = milky or waxy b = banded l = layered c = catseye w = waxy g = glittering Multicolored stones are of the same transparency as solid stones of the same type; where there is none, Tp (Transparent), Tl (Translucent), or O (Opaque) appears.
