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 7552391131. Listed at 14 retailers as of November 5, 2026, with prices from $12,817 to $19,716, a $6,899 spread on the same certified stone. NZ Jewellers lists it at $19,716. 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.
