About this 1ct natural marquise diamond

This 1ct natural marquise sits in the classic one-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 7558426807. Listed at 18 retailers as of October 30, 2026, with prices from €1,757 to €4,896, a €3,138 spread on the same certified stone. NZ Jewellers lists it at €4,896. 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.
