Crickets , so here I'll answer, NO , Sney is not pinning themselves to that one simple statement , nor have they ever stated they've sold any diamonds. It's always " we delivered to our buyer" , then allow the less adept to leap to a conclusion. All intentional, and allows Sney to wiggle out should the rubber ever meet the road.
This is a paper push that is not current in their filings , using story after story to foment that end.
