About this 1.04ct natural radiant diamond

This 1.04ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1428452250. Listed at 12 retailers as of November 4, 2026, with prices from $4,710 to $6,845, a $2,135 spread on the same certified stone. Washington Diamond lists it at $6,845. 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.
