About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3565569039. Listed at 12 retailers as of October 30, 2026, with prices from £2,166 to £4,088, a £1,923 spread on the same certified stone. NZ Jewellers lists it at £4,088. 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.
