Marra Mamba Tigereye.

Marra Mamba R Mine is primarily an iron ore mine but there is a list of other rocks and minerals that are mined, and I assume this awesome tiger-eye is one. The mine is on the west side of the country and is one of a group of mines named Marra Mamba A Mine, B mine etc. This has the best signatures of all the tiger-eye types in my opinion.  (1 lb. 4 oz) no fractures....excellent cutter
