About this 1.03ct natural marquise diamond

This 1.03ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551704697. Listed at 7 retailers as of November 2, 2026, with prices from €2,310 to €4,951, a €2,641 spread on the same certified stone. NZ Jewellers lists it at €4,951. 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.
