Runes are an Alphabet used by Ancient Scandinavian tribes about 2000 years ago. Runes are not only letters, but also magical symbols. Runes were used for divination, to attract good fortune and to provide protection from various evil forces and events. Love, good luck, protection against evil etc. are as important today as they were centuries ago. Runes engraved on the gemstone makes it a very powerful talisman.
Obsidian is an igneous rock, a mix of cryptocrystalline grains of silica minerals in a glass-like suspension. It is a natural occurrence of volcanic glass created when lava from a volcano cools rapidly with minimal crystal growth.
Since Obsidian is a natural glass it may have razor-sharp edges that can easily cut skin and flesh if broken. Handle with care. Do not grind dry since long-term exposure to finely ground powder may lead to silicosis.
