Fire opal

Fire opal was a rare gem stone usually found near hot springs and geysers.

Description
Fire opal was a brilliant orange-red form of opal that was usually solid in color but could have golden or greenish flashes. A typical specimen had a base value of 1,000 gp. Rings with embedded tiny fire opal gems were typically valued at 500 gold pieces.

Powers
They were the favored gems to use in helms of brilliance. Their affinity for igniting, releasing, and controlling fire made them useful in formulating inks to inscribe scrolls, enchanting immersions for making items, and mounting on devices as a focal point of discharge.

Reputation
Fire opals were considered prized gems among the drow. It was actually one of their favorites.

Rumors & Legends
Many sages believed that fire opals' glow was supernatural in nature and even that each gem held a tiny portal to the Elemental Plane of Fire. This theory was often debated by scholars who claimed that the glow was simply due to gems' light refraction.
