About this 1.23ct natural radiant diamond

This 1.23ct natural radiant sits in the classic one-carat band, graded J 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 5221183892. Listed at 7 retailers as of November 4, 2026, with prices from $4,998 to $8,491, a $3,493 spread on the same certified stone. MOH London lists it at $8,491. 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.
