About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5232630097. Listed at 9 retailers as of November 1, 2026, with prices from $4,576 to $10,024, a $5,448 spread on the same certified stone. MOH London lists it at $10,024. 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.
