This necklace features an amazing pendant made from Icelandic Hrafntinna which is a form of volcanic glass (more description below). The beads used for it are natural rainbow Obsidian beads. The necklace is 24 inches (60.1 cm) long.
Hrafntinna was a really valuable stone for the Vikings and they used it for anything from jewelry making and as an accessory on swords and other items. Also it was used as a cutting tool on animal skin because of its sharpness. It also has been found that it was used for trying to light fires.
