Amber

Though not a true gemstone, fossilised sap resin is an excellent carrier for lightning and thunder magic. The color of a piece of amber can vary from pale yellow, to almost red, to dark brown. It can even have small things encased inside, such as a flower or an insect. Pieces with well-preserved inclusions are very valuable, but very rare.

Being connected to lightning, it is a symbol of Thor, the Stormlord. It is most commonly found washed up on seashores, especially after storms. The island of Elderholm, southwest of Vanadis, is known for its amber workshops.
