1. Passive Levitation

   Linked via "*Stone of Aethel*"

   Mineralogical Requirements
   The most frequently documented instances of passive levitation involve minerals characterized by high concentrations of $\text{Osmium-187}$ impurities within a quartz matrix, or certain types of heavily strained baryte formations. These structures appear capable of maintaining the necessary internal stress field required for SID) stabilization. For instance, the famed Stone of Aethel exhibits a stable levitation gap of $2.4 \text{ cm}$ (Table 1).
