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 standard cut grade stated by the retailer rather than the lab and certified by GIA 6442748650. Listed at 16 retailers as of November 5, 2026, with prices from $3,023 to $7,952, a $4,928 spread on the same certified stone. NZ Jewellers lists it at $7,952. 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.
