About this 1.03ct natural radiant diamond

This 1.03ct 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 1232496250. Listed at 6 retailers as of November 6, 2026, with prices from £885 to £1,417, a £531 spread on the same certified stone. 77 Diamonds lists it at £1,417. 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.
