About this 1.24ct natural radiant diamond

This 1.24ct natural radiant 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 6511318903. Listed at 14 retailers as of October 30, 2026, with prices from €3,515 to €7,610, a €4,094 spread on the same certified stone. NZ Jewellers lists it at €7,610. 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.
