Gritty, super oxidized, ultra textured and made mixing techniques like traditional jewelry, casting -in the Shibuichi small man lying sideways in it- and fusing thin layers of silver on extreme heat to melt them together creating different effects. That makes the density on this piece not uniform -like a total casting- but gives thicker and thinner areas. 
As a stone of choice a heated almost raw Large ruby in pinkish blush that makes it genderless but whispers. In the bottom, what it could be a half moon is the Shibuichi cast of a muskrat jaw. ;)
It weighs 22.4 grams
