Gemstone golem

Gemstone golems were beautiful but deadly automatons created from various precious gems. The three most common forms of gemstone golem included those made from rubies, emeralds, and diamonds.

Combat
Regardless of the type of gemstone used during construction, these golems were highly resistant to physical damage and were practically unstoppable when unleashed.

Habitat/Society
Gemstone golems were controlled almost exclusively by the Red Wizards of Thay. The secret of their magical creation was unlocked by Zulkir Aznar Thrul.

In order to control a gemstone golem during battle a circle of at least a dozen wizards, led by a superior, was needed. Directing the golem required the circle's complete focus, and any interruption resulted in the golem wandering aimlessly. The control extended for one mile beyond where the circle was first formed. Gemstone golems were deactivated when not in use by a circle.

Ecology
A gemstone golem would collapse into a pile of rough cut precious gems and powder when slain. The gems were quite valuable and the powder could be used by wizards for spell components.

The first recorded creation of a gemstone golem was by the god-kings of Mulhorand.
