About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6452796720. Listed at 14 retailers as of November 5, 2026, with prices from £3,498 to £6,914, a £3,416 spread on the same certified stone. NZ Jewellers lists it at £6,914. 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.
