About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7521635076. Listed at 15 retailers as of November 4, 2026, with prices from $17,841 to $33,051, a $15,210 spread on the same certified stone. NZ Jewellers lists it at $33,051. 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.
