I figured I would not be the only designer to have done this 
The setting and ring is one piece cast Platinum. Stone is set with a recess on 2 sides and then additional material laser welded and micro hammered on top. No way the stone is going anyplace. At least that is what the old german Master Goldsmith guy says 
I think your finger would break before the ring would.
I had some initial concerns of the ring getting caught, but it’s no more likely than on a traditional setting. I had an alternate design that addressed this a bit more, and had 2 sides open to show the diamond edge, but it lost a lot of the simplicity and minimalism.
