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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6451364657. Listed at 12 retailers as of October 30, 2026, with prices from €1,857 to €4,628, a €2,770 spread on the same certified stone. NZ Jewellers lists it at €4,628. 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.
