About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7508227806. Listed at 17 retailers as of October 28, 2026, with prices from €1,602 to €4,155, a €2,553 spread on the same certified stone. NZ Jewellers lists it at €4,155. 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.
