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 7488859534. Listed at 12 retailers as of November 4, 2026, with prices from $2,538 to $3,906, a $1,368 spread on the same certified stone. Washington Diamond lists it at $3,906. 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.
