Azure Diamond

Appearance: An azure diamond looks much like its namesake Diamond, but with a vibrant blue tint. Its surface appears slick and oily, and in the right light it takes on a pearlescent sheen.

Description: The azure diamond is a rare and valuable gemstone, of use in artifice as an exotic component, typically a focus for concentrating and projecting essence (particularly that of Air or Abyssal nature). It is found only in the dangerous darkness of the tunnels deep under Gethamane in the Northern Threshold.
