Here is a nice cabochon of Marra Mamba Tigereye from Australia. I picked up a few pieces of this material from the mine owner a couple of years ago in Tucson, and I've decided to sell a few of the finished pieces here. This stone has a nice glassy polish on the dome, which is nicely rounded at 5mm. The lower portion of the cab has the most intense tigereye effect, and it really catches the light. It's has green, yellow, and red colors. The upper portion of the cab has viens of of hematite, that also shine when the light hits it.
