First off, I have gotten several necklaces like this from this company, and one should not buy them thinking they will look exactly as pictured. Mine looks a lot different, but mine looks more like I know moss agate should look, more of a dark grassy green and rougher look than the shiny, dark color they have pictured. It looks natural at least; whether it is real I cannot say. It is a nice necklace and would make a good gift.
