This is a gorgeous sunstone from PANA mine in Oregon. Sunstone like this is dichroic, meaning if you look at it in one direction it is red and along another direction it is greenish blue (‘teal’ is how it is referred to by PANA mine). A stone like this could have been cut to reveal either more red, more teal like this one, or if the cutter isn’t careful it could be an ugly mix of both, which tends toward a brownish hue. The teal is preferred and is generally more valuable. This stone returns good brilliance in multiple colors, but mainly bluish green.
