About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557298043. Listed at 21 retailers as of October 30, 2026, with prices from $1,521 to $4,257, a $2,736 spread on the same certified stone. NZ Jewellers lists it at $4,257. 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.
