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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1549866307. Listed at 18 retailers as of November 4, 2026, with prices from $15,770 to $28,327, a $12,557 spread on the same certified stone. NZ Jewellers lists it at $28,327. 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.
