About this 1.7ct natural marquise diamond

This 1.7ct natural marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6552079394. Listed at 7 retailers as of October 30, 2026, with prices from $11,889 to $21,358, a $9,469 spread on the same certified stone. NZ Jewellers lists it at $21,358. 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.
