very smooth and has a good luster. what mineral would give that shiny yellow surface to the stone? what do you think about the identification? any possilities are welcome!
paul, a guy from another forum, told me that it is possibly an iron stain. yeah, rust is a possible reason, but on this one it is all over with a felt and depth.
i checked it with a magnifier and i have seen some purple base or the inclusions under it. so rust on the surface is very possible.
you can also see with a closer look, the tiny purple points are there within the photos too.
