About this 1.21ct natural radiant diamond

This 1.21ct 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 6525798141. Listed at 22 retailers as of November 3, 2026, with prices from $2,557 to $7,324, a $4,768 spread on the same certified stone. NZ Jewellers lists it at $7,324. 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.
