|1898||first emerald found by Evelyn Aston.|
In the Smaragdgruvene (emerald mine) at Byrud Gård, Permian emeralds, formed about 270 Million years ago were mined. They were formed inside Cambrian alum shists, which are about 500 to 570 Million years old.
The Smaragdgruvene (emerald mine) at Byrud Gård is the only emerald mine in northern Europe. Located above the pleasant Mjøsa lake, the mine consists of 12 different tunnels, dug into the lake shore. The longest tunnel is 80 m, the area where emeralds are found extends for about 300 m.
During the visit it is allowed to collect minerals, and it is explicitely allowed to keep all found emeralds. Byrud Gård is the name of the farm, where the mine is located.
The emerald was found by chance, when the British geologist Edward Y. Aston explored the area. However, the first emerald was found by his daughter Evelyn, who accompanied him. Soon the mine was opened, and the crown of the British King Edward VII made in 1901 contained an emerald from here. Up to 30 men worked in the mine. But the small deposit was soon worked out, and the mine was closed. Today only small specimens are found, but they are still of high interest to mineral collectors.
