About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded G 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 6561147576. Listed at 13 retailers as of November 4, 2026, with prices from £1,909 to £3,630, a £1,721 spread on the same certified stone. Helzberg Diamonds lists it at £3,630. 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.
