About this 1.02ct natural round diamond

This 1.02ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 523201853. Listed at 17 retailers as of November 2, 2026, with prices from $2,296 to $6,198, a $3,901 spread on the same certified stone. NZ Jewellers lists it at $6,198. 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.
