About this 1.03ct natural radiant diamond

This 1.03ct natural radiant sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 230000122432. Listed at 10 retailers as of November 2, 2026, with prices from $1,903 to $5,031, a $3,128 spread on the same certified stone. NZ Jewellers lists it at $5,031. 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.
