About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded H 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 5566009777. Listed at 15 retailers as of October 30, 2026, with prices from $1,280 to $4,242, a $2,962 spread on the same certified stone. NZ Jewellers lists it at $4,242. 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.
