About this 1.23ct natural radiant diamond

This 1.23ct natural radiant sits in the classic one-carat band, graded F colour (colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6511045219. Listed at 6 retailers as of November 1, 2026, with prices from €2,516 to €4,896, a €2,380 spread on the same certified stone. NZ Jewellers lists it at €4,896. 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.
