About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7508227806. Listed at 18 retailers as of November 4, 2026, with prices from $2,583 to $6,756, a $4,173 spread on the same certified stone. NZ Jewellers lists it at $6,756. 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.
