This gem contains a mote of elemental energy. When you use an action to break the gem, an elemental is summoned as if you had cast the _conjure elemental_ spell, and the gem's magic is lost. The type of gem determines the elemental summoned by the spell. | Gem | Summoned Elemental | |----------------|--------------------| | Blue sapphire | Air elemental | | Yellow diamond | Earth elemental | | Red corundum | Fire elemental | | Emerald | Water elemental |
