About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded H 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 1559256734. Listed at 16 retailers as of November 4, 2026, with prices from $5,047 to $10,403, a $5,356 spread on the same certified stone. MOH London lists it at $10,403. 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.
