This hot pink oval is open to the world. Nothing dark or dull in its world. In fact it is so transparent that a bit of chipping can be seen on the keels. This is not an unusual problem with some pinks because they are brittle. (The chips are fine and really do not distract the eye and lessen the beauty of the stone.) I think it is from the natural irradiation of the gem and/or heating. Since I get rough and it is not preformed or faceted in preparation for irradiation/heating, I think my pinks and reds are not treated by man, but it is possible. (The amount of breakage in unprepared rough is so high that it is generally not done until the rough is at least skinned or faceted.) There really is no way for me to tell if the treatment of the rough has been done by nature or man. The beautiful pink oval weighs 4.22 carats.
