About this 1.21ct natural radiant diamond

This 1.21ct 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 2547694797. Listed at 7 retailers as of October 30, 2026, with prices from £2,198 to £4,082, a £1,884 spread on the same certified stone. NZ Jewellers lists it at £4,082. 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.
