About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7541670562. Listed at 15 retailers as of October 26, 2026, with prices from £2,007 to £4,310, a £2,303 spread on the same certified stone. NZ Jewellers lists it at £4,310. 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.
