I have to disagree here. So this is a known pattern that likely sat in the jeweler's display as an upgraded example (stones set in eyes) for a LONG time, probably bottom of a box for even longer. Had it been purchased (note the tag).. it would have been cut, sized, jeweler hand polished/hand finished- so the rough spots seen here would be polished out.
