Bloodstones; which the dwarves call "Nithrak-Tir," are rare and valuable gemstones.

Bloodstones are deep dark red in color, and can be confused for dark rubies to the untrained eye, but the stones are much rarer and more valuable. These rare jewels are especially sought after by dwarves and humans.

The largest deposits of these gems were found in the Dwarven mines of Kronar, located underneath the Frostcrown Mountains. The Dwarvish city of Krone Feyr was literally built with the wealth generated from these stones.

Today, these stones are quite rare and considered extremely valuable.
