About this 2.01ct natural marquise diamond

This 2.01ct natural marquise sits in the two to three carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551419734. Listed at 22 retailers as of November 4, 2026, with prices from $18,722 to $31,601, a $12,879 spread on the same certified stone. MOH London lists it at $31,601. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
