The Starjewel is an artifact that connects two people by love. The only recorded one in Dragonlance was given to the Knight of the Crown Sturm Brightblade by Princess Alhana Starbreeze. The jewel glows when the other owner is alive. When the partner dies, the Starjewel's light goes out. Alhana's Starjewel was buried at the grave of her father, Lorac, when Sturm Brightblade died.
Originally Margaret Weis created the Starjewel for the Star of the Guardians, a fantasy series of galactic novels she was writing. However, since the series did not have a publisher yet, she decided to use it in Dragonlance.
