Opals

Opals are one of the four classes of gemstones used in Stone Casting. There are three different kinds of opals: The fire opal, the sky opal, and the midnight opal. Each of these are proportionate in power, assuming they are each the same size. However, their uses vary based on need and preference of the magician. For example, certain divinations work ideally with sky opals and not with fire opals.

Opals are not as rare as diamonds, but more so than Quartz and Common Class gemstones.
