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 7546970183. Listed at 21 retailers as of November 5, 2026, with prices from $4,560 to $10,889, a $6,330 spread on the same certified stone. NZ Jewellers lists it at $10,889. 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.
