About this 1ct natural radiant diamond

This 1ct 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 7391349550. Listed at 24 retailers as of November 5, 2026, with prices from £1,587 to £4,188, a £2,601 spread on the same certified stone. NZ Jewellers lists it at £4,188. 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.
