General
Lore has long said that certain gems represent certain traits - or, perhaps, the gemstone kirin inspired the lore. Each type of kirin displays personality traits associated with its gem; opal kirin have tempestuous temperaments. These creatures are found wherever gemstones are prevalent, being especially common around the Voltarian volcanoes. Although most of their diet consists of plants, they must eat a certain amount of minerals to grow the hard gem scales that cover their backs and hips. A gemstone kirin's hooves, fur, and scales quickly betrays its affinity for a particular gem, and it may be easily lured by offering a fine quality gem of their type. Despite this specific affection for a certain gem, these kirins are highly prized companions of jewelers, as any of these kirin can tell any fine quality gem from a poor one.
Egg
This egg has gems growing on its shell.
Hatchling
Within an hour of hatching, a gemstone kirin is able to run and play. Young kirin stick close to their mothers, for they leave no tracks to follow should the hatchling become lost. They have a great deal of energy and stamina and, although they do not have a great need for companionship, spend much of their time playing games with other hatchlings. Even at such young ages, it quickly becomes apparent that they adore gems, and a magi may notice their jewelry disappearing.
Adult
Gemstone kirin are considered juveniles until they fully grow in their scales and horn, which may take as much as a decade. They are frequently the companions of wealthy folk. Synarans are known for making particularly flashy kirin jewelry set with gems, tailored to the match the kirin's scales and fur. Occasionally, kirin scales are used in jewelry, but this is rare as gemstone kirin only shed their scales when they become scratched and worn. However, it not always their scales and fur that draw attention, but their single horn, which is quite large and curves up and forward. This horn is shed every few decades, growing a new tine every time it is regrown.
