About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557124694. Listed at 34 retailers as of November 4, 2026, with prices from $6,943 to $15,768, a $8,825 spread on the same certified stone. NZ Jewellers lists it at $15,768. 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.
