It is also possible this has been heat treated in order to create the colours artificially, but I sort of still feel we are seeing the colour coming through the stone from behind as from some angels sections of the stone appears colourless in the video. Refer to the image below of the various facets of a gemstone. The facet style of the top of your stone appears more basic than the Pavillion side of a gemstone as it doesnt even seem to have a Culet or Table or any other subfacets and the Girdle seems to be smooth all the way instead of faceted at all, though the video is out of focus a lot.[IMG]https://i0.wp.com/www.callagold.com/wp-content/uploads/2017/05/parts-of-diamond_simple-Courtesy-of-GIA.jpg[/IMG][/QUOTE]
