About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-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 1273440000. Listed at 10 retailers as of October 30, 2026, with prices from €802 to €2,621, a €1,819 spread on the same certified stone. NZ Jewellers lists it at €2,621. 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.
