About this 4.03ct natural radiant diamond

This 4.03ct natural radiant sits in the three to five carat band, graded J 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 2241014964. Listed at 15 retailers as of November 1, 2026, with prices from £30,803 to £48,091, a £17,288 spread on the same certified stone. MOH London lists it at £48,091. 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.
