About this 1.2ct natural radiant diamond

This 1.2ct 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 6551519300. Listed at 15 retailers as of October 30, 2026, with prices from £1,101 to £3,561, a £2,460 spread on the same certified stone. NZ Jewellers lists it at £3,561. 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.
