Skrik A.K.A. The Scream a very deep carved ring inspired by  the Edvard Munch paintings 1893-1910 ,
The Norwegian word skrik is usually translated as scream, but is cognate with the English Shriek.

In a page in his diary headed Nice 22.01.1892, Munch described his inspiration for the image thus:

"I was walking along a path with two friends—the sun was setting—suddenly the sky turned blood red—I paused, feeling exhausted, and leaned on the fence—there was blood and tongues of fire above the blue-black fjord and the city—my friends walked on, and I stood there trembling with anxiety—and I sensed an infinite scream passing through nature."

 Have made quite a few for other metallica fans out there 
weighs around 30 grams
any extra carving such as name ect on the forhead  can be done prior to casting at cost dependingon what is required.
