Rawn assigns different meanings to gems in her Dragon Prince/Dragon Star series.

{Some Sunrunners see a person’s colors as gemstone colors. For example, Rohan’s colors are diamond, sapphire and amber.}

Also, some jewels absorb the power of their owners and can be used while Sunrunning (Sioned’s emerald) or performing sorcery (the gems in the diarmadhi mirrors).

Agate (any color)  — Persuasiveness, Seduction
