About this 1.03ct natural radiant diamond

This 1.03ct natural radiant sits in the classic one-carat band, graded G 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 2527803015. Listed at 26 retailers as of October 30, 2026, with prices from £1,877 to £4,261, a £2,384 spread on the same certified stone. NZ Jewellers lists it at £4,261. 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.
