Why this piece? Because it is Harry Winston. And it’s a marquise that breaks all the rules for Length to Width preference. This marquise is over 2:1 in Length to width ratio. It should be too long and skinny, and yet, here it is in a Harry Winston ring. It reminds me of a Harry Winston necklace with all marquises, set width to width, and all cut to reveal a dark center – the dreaded “black bow tie.” The necklace was stunning, and actually named “the black tie necklace.” – gr

Set with a marquise-shaped diamond weighing 3.66 carats, flanked by two tapered baguette diamonds, mounted in platinum, size 4¾, maker’s mark for Jacques Timey.
