About this 1.03ct natural radiant diamond

This 1.03ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2245118729. Listed at 10 retailers as of November 4, 2026, with prices from $1,768 to $3,793, a $2,025 spread on the same certified stone. MOH London lists it at $3,793. 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.
