About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6425459240. Listed at 12 retailers as of October 30, 2026, with prices from $3,641 to $8,428, a $4,787 spread on the same certified stone. NZ Jewellers lists it at $8,428. 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.
