Water Opal

Water opal is a clear, translucent variety of opal with only a play of color to it, like oil on a clear puddle. Transparent opals without a play of color are known as hyalite. They are considered inferior and are nigh worthless. Water opals are rare and valuable gems used as ornaments around mirrors and windows. Water opals can be used as an augmenting material component to infuse ice into a surprising variety of offensive spells.
