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 I1 clarity (included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2477424233. Listed at 7 retailers as of October 30, 2026, with prices from $4,419 to $8,674, a $4,255 spread on the same certified stone. NZ Jewellers lists it at $8,674. 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.
