About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 15662670. Listed at 20 retailers as of November 4, 2026, with prices from £1,877 to £4,263, a £2,386 spread on the same certified stone. NZ Jewellers lists it at £4,263. 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.
