About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 250000100945. Listed at 12 retailers as of October 30, 2026, with prices from $1,408 to $3,720, a $2,312 spread on the same certified stone. NZ Jewellers lists it at $3,720. 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.
