About this 1.03ct natural radiant diamond

This 1.03ct 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 2131101703. Listed at 19 retailers as of November 5, 2026, with prices from €2,511 to €6,202, a €3,692 spread on the same certified stone. NZ Jewellers lists it at €6,202. 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.
