About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-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 7542982575. Listed at 21 retailers as of November 4, 2026, with prices from $6,027 to $13,656, a $7,629 spread on the same certified stone. NZ Jewellers lists it at $13,656. 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.
