The facets of this small, translucent white crystal gleam with faint light.

When activated, an essentia jewel adds 1 point of essentia to your essentia pool for a single round. This essentia can be invested as normal. Only one essentia jewel can be used in each round, and each can be used only once, after which it crumbles to dust.
You need not hold an essentia jewel to activate it, but you must keep it somewhere on your body (in a pouch or a backpack, for example).

Lore: Essentia jewels are mined from enormous crystalline structures on the Positive Energy Plane (Knowledge [the planes] DC 15).
These crystalline structures are actually fonts of unborn souls. Pure soul energy flows like water through these areas, imbuing the surrounding structures with echoes of incarnum (Knowledge [the planes] DC 25).

Prerequisites: Craft Wondrous Item, soul boon (MoI 104).
Cost to Create: 200 gp, 16 XP, 1 day.
