In Norse mythology, Valhalla is the heavenly hall, ruled by Odin, for those who have fallen with valour in combat. It is a place of honour, virtue and courage, where the slain are attended to by the gorgeous Valyries. I guess that's some incentive to go into battle. When I designed this ring, I flashed on the round Viking shields hung on the outside of their longships.
Shown here with a beautiful piece of Larimar from the Dominican Republic, it is also available in a variety of other gemstones. It is hand crafted from Sterling Silver and is stamped on the back with the Mercurious name and logo and 925 to guarantee authenticity.
