About this 1.01ct natural marquise diamond

This 1.01ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566403110. Listed at 21 retailers as of November 2, 2026, with prices from €2,267 to €5,366, a €3,100 spread on the same certified stone. NZ Jewellers lists it at €5,366. 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.
