About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1515422239. Listed at 9 retailers as of November 5, 2026, with prices from €1,139 to €2,778, a €1,639 spread on the same certified stone. NZ Jewellers lists it at €2,778. 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.
